@SankalpLearningSolutions #plantkingdom #biologyclass11
So guys in the last session we were discussing regarding the concept of plant kingdom right yes okay fine so in the plant kingdom we discussed some concepts of Al and also we discussed the some commercial uses of Al also all right so let us discuss the other parts or other part of
Classification in this class and then let us solve some multiple choice question related to so those Concepts fine yeah okay fine so when we come to the classification of Alig the Alig is classified on chloro that is green Alig fopa Ro red based on the dominant pigment present in it based on a
Dom the Alig has been divided into chlorop fopa and R chloro chloro is there that only indicates that chloroplast will be present along with the chlorophyll A and B so dominant pigments chlorop and so those organisms will be unicellular that is they will be having a single cell Colonial and filaments then
Chloroplast the chloroplast will be disy in shape dis shape spiral form of a spring or a ribbon shaped chloroplast will be present they will store the food or they will store the substances pyoid substance materials so these pyoid will be seen in the chloroplast only okay then the cell
Wall when we come to the boundary the cell wall will be made up of inner layer cellulos outer layer pecto so this is regarding chloro fine so reproduction vegetative reproduction will be by frag m mentation a sexual reproduction will be by Zeus spce sexual reproduction so Isam condition here the gamuts will look
Similar same in structure morphologically similar compar to male G reproduction chloro so let us solve some questions now okay I think when 10 questions don’t know last time Sol did we answer that yeah so today’s first question is are useful to man option a fixation of almost half of
Toal total carbon dioxide on Earth option b primary producer option C increase level of oxygen option D all of these yes the first answer is given by Rashmi then Priya okay what about others many students are present no sanot ktim Aishwarya Shivam morti then uh B GAA okay what about your
Response please do message your response option A San ktim answer it as option A okay what about others awara shivy and one more be fast be fast yes my dear YouTube students so here fixation of almost half of total carbon dioxide will be done by Al primary producer will be Al because
In water or in aquatic medium primary producer what we say the producer in the food chain starting tropic level so that will be level of oygen it will be more due to photosynthesis how so option D is the right answer guys option A a option D all of these is a
Right answer what is the answer option D all of these next question hydroides are produced by hydroides are no substances G so Hydro option a brown that is alen kagin red Al Ager Brown Al option B Brown Al algen red Al kagin option C Brown Alig red Al option D none
Of these hydroides are produced by any responses here okay the first uh answer is given by awara as option C okay good Priya as option C good what about others fine be fast be fast guys so hydroides and these hydroides are nothing but they are used during the
Transportation of plant links okay or small plants plant links the large is not Necessary hydroides have been attached to those roots hydroides are the substances which are used for the transportation of the plantlets okay so let me show you let me explain you that red and brown Al so remember this example guys uh fresh water example ws and clamas fresh water Al which are available in
Fresh water which are seen in fresh water next is stagnant water next running water clora otrix okay when we come to the phop phop so or a brown Al these are Marine habitats Marine habitat means these are found in salt water next these vary in shape and size from simple
Branched filamentous form so poop BR simple branch example ectocarpus ectocarpus two profusely branched forms around then body consist of it consists of first to hold fast then stock s and and front I repeat hold fast stalk sttip and front next they will be having the pigments like chlorophyll a chlorophyll C chlorop
Kenites xant toils fantin soan fan pigments so these contribute more for the brown color next food is stored as carbohydrates in the form of laminer or manate food is stored in the form of carbohydrate form that is glycogen plants carbohydrate form that is St Brown Al food is stored as a
Carbohydrates in the form of laminarian or manitol then cell is covered by algen a gelatinous CO coting so Brown now let us see about uh the hydroides yeah here you can see the fourth Point guys fourth Point Alin the wall layer of I’m sorry the wall layer of brown alate
It is a red so these both substances are there these both substances are used as hydroides which is fibrous in structure fibrous in structure it holds water for a longer time and used to transport the seedlink or a plantlets okay so that is regarding the hydroides Road
Of then we will again solve certain multiple choice question see here sea water Al ectocarpus vegetative reproduction It Is by fragmentation aexual reproduction by bagate zoospores sexual reproduction by isog gamus an isogamous or ug gamas in nature examples here are ectocarpus diota laminaria sasm and fcus so some of
The examples are edible also like s next when we come to the Roo PCA it is considered as a red Al it is found in fresh water braish water D salt water so the pigment presents here present in this Al are chlorophyll A and B sorry chlorophyll A and D I repeat
R pigment present due to this pigment the Alig appears red in color next food is stored as Floridian starch which is similar to amop pectin and glycogen in structure so fop could be stored in STO stor as manol vegetative reproduction is by fragmentation aexual by non-motile Sports sexual also by nonmotile gamuts
Example polyphonia porir gracilaria and gelidium so these all are the examples now let us solve some questions yes YouTube students okay so the answer for this is most of you answer it as option uh c yeah option cwar Priya answered it so option C Brown Alig Alin then sorry
Option b is the right answer Brown Alig Alin red Alig kajin just a minute okay Brown Alig algen red Alig kagin option b is the right answer here next question choose correct statement Okay chlorella a multicellular Al rich in protein chlorella and spirulina are astronaut foood because of their High carbohydrate vitamin mineral but less protein the product obtained by grasil areia are used to grow microbes laminaria and sasm a member of Roo P are among 70 species of marine Al used as
Foot they asked choose correct statement what is your response guys yes be fast be fast yes my dear YouTube students yes only one uh student answered it what about others good good yes YouTube students okay add on the YouTube awara it is a simple question you have to just select the correct
Statement related to the AL okay from YouTube Sanji is active very good fine fine so choose correct statement here here what happens chlorella a multicellular algae rich in protein they said chlorella and spirulin are astronaut put they set so some of you answered it as option C an B GAA answered it as
Option C then uh someone answered it uh Rashmi answered as option D okay see here chlorella multicellular AR rich in protein chloral and spinar Astronaut foot the product obtained by grass area are used to grow microbes so here when you study the economic importance of Alig then you will understand
This yes YouTube students yeah see here chlorella and spirulina are rich in proteins but in the question they have given Less in protein so that is wrong then uh porer lamania and sasm only these three are used as foot not more than 70 species are used as foot so
That is also a wrong statement gelidium gracilaria corras are used to grow microbes make ice creams and all then Ager agur is used as commercial product so here the right answer is the product obtained by grasil area are used to grow microbes is the right answer okay option C that is chlorella
Multicellular ala rich in protein it is not a multicellular Al so it is wrong then after that Chlor Spina even though it is used as astronaut foot it will be rich in protein L protein Lin use but among 70 species of mar are not edible so this is also Al wrong
Statement so the remaining statement is option C so that is a right answer next question chlorop are commonly called as chlorop option a green Alig B blue green Alig C Brown Alig d red Alig good yes YouTube students okay B GAA answered here Rashmi answered Aishwarya Shivam morti answered
And from the YouTube who all answered it Priya answered here okay option a green Al is a right answer blue greenia BR red roo so option a green Al is a right answer next question major pigment of camidas clamas major pigment y option A chlorophyll A and B option b Chlor
Chlorophyll A and C option C chlorophyll A and D option D pantin and Pico Erin so here you have to answer after that you can guess the answer be fast yes you students be fast all of you should respond major pigment of clamy domas slamy major pigment okay I got first quick answer
From Rashmi so she answered as option A yes YouTube students only one participant there are many students ala chitra is here Priya is here Aishwarya Shivam morti is here B GAA is here only Rashmi answered the question what about others be fast guys yes Priya answered it awara Shivam morti
Okay fine so option a good major pigment green is green Al clonas is an example of green alga yes San you are right option A chlorophyll A and B is a right answer next question choose incorrect state about green so stat we have to select wrong statement related to Green Al option A
The chlorophyll localized in definite chloroplast spyroy have spiral chloroplast most member have one or more storage bodies that is pyoid localized in the chloroplast option D cell wall is made up of outer layer that is of cellulose inner layer layer of vectos which is the wrong statement among the following yes YouTube
Students be fast be fast okay Rashmi answered as option D fine what about others what about others yeah B GAA answered as option b okay yes YouTube students so they asked wrong statement chlorop localized in definite chloroplast chloroplast chlorop that is a right statement Spyro have spiral chloroplast
Chloroplast that is also a right statement most member have one or more storage bodies so chloroplast one so it might be having more than one pyoid so that is also a correct statement D the cell wall is made up of outer layer that is of cellulose inner layer
Pecto that is a wrong statement because inner layer will be cellulose outer layer will be pecto okay so option D is a wrong statement related to Green alga option option D is a right answer here next question reproduction in green Alig are isog gamas an isog gamas ugas all of these green
Al I got the first quick answer from Rashmi yes YouTube students answered it as option D from YouTube great yes what about others B GAA answered it as option D good yes guys be fast until you miss message no the session will not be interactive it I feel like I’m only talking to
Myself so the right answer is here option D all of these option D all of these is a right answer next question Cara is or Chara is common Stone word marine green Al unisexual Al none of these Tara is an example of what yes YouTube students awaria shim morti answered it
As option b okay good what about others Rashmi answered it good yes YouTube students B GAA answered it good secure see cha is a uh green algae that is it comes in a chloropia where it comes it comes in a chloropia here you can see fine so see
Here it is profusely branched and if you look if you look you can you feel that it is made up of many layer and it is a stag magnet water Al right so when you check the answer here they asked common Stone word marine Alig is
Wrong common Stone word is wrong uh then none of these is wrong unisexual Al okay it is a stagnant water Alig so option b is wrong so option C unisexual Al is the right answer next question flagellation in green Al is for the movement of a Ze for okay so 2 to
A equ and they are EP ep the region they are found these areal and lateral 2 to eight equal and lateral option D absent okay the quick answer is given by Aishwarya Shivam morti Rashmi yes YouTube students Sanji from YouTube okay yeah be fast be
Fast so option A 2 to8 equal and epical is the right answer guys next question FCA is commonly named the other common name of PCA green Al Brown Al red Al none of these the quick answer is given by Aishwarya Shivam morti Rashmi as well as
Bea very good great going so option b uh Brown Alig is the right answer it is well and good if all of you who are present in the session if you answer it most of them are answering and some of them simply sitting I don’t know whether
Are they watching movie here no now so please do respond guys okay do respond next choose the correct statement yes Sanjay from YouTube answered it as option C an it is not option C it is option B Brown Alig next question choose the correct statement from the following correct statement select
Ectocarpus is filamentous form while Kelps is profusely branched Kelps May reach a height of average 100 cm plant body of brown Alig attached to substratum by strip Leaf like photosynthetic organ of brown Alig is strip you have to select correct statement the quick answer is given by
Aishwaria Shivam morti and then B GAA okay expected fine what about others Rashmi answered it as option A Fine guys they asked correct statement okay so the plant body of brown Al attached to substratum by stripe Al by hold fast by hold fast it will be attached then Leaf like photosynthetic
Organ of a brown Al is not called as stripe is called Lamela then after that Kelps May reach to a height of average 100 cm it is not 100 cm it is 100 m it is 100 m so the right answer is here ectocarpus is a filamentous form
While kelp is a profusely branched example of an Al option A is a right answer read the question properly understand the question slow slowes next question yes YouTube students yeah major pigment found in fucus is option A chlorophyll A and C option H option b chlorophyll A and D option C chlorophyll
A and B option sorry or option C chlorophyll A and B option D fuco xanthin and P Erin B answered it quickly as option C okay fucus first you should know to which Al to which Al the fucus belongs to fucus can answer the question answered it good what about others yes YouTube
Students fine so chlorop A and C A and Bashi also answered it as option A so fucus let us see to which uh classification or to which alligate this fucus belongs to see here the fucus belongs to an Al that is poopa or brown Al in brown Al
Chlorophyll A and C keratinoid xops and fuco xanthin will be the pigments so in the question they have given as very good in the question they have given as which pigments are present I think first at first the correct answer is given by uh uh B GAA I guess so option A
Chlorophyll A and C option A chlorophyll A and C is a right answer a and c f it is a F5 CA so option A is a right answer uh fine yeah B Goa awar answered it okay option A is the right answer next question the color of brown Al depend on
Brown amount of xano fuco xanthin present in them Pico Arin and fuco xanthin a and b both the color of brown alligate depend on the first quick answer is given by B GAA okay Rashmi answered it Priya answered it what about others I’m sorry okay so just glance this
Point they asked Brown Al body consists of hold F talk Ty and front pigments chlorophyll A and C kenites zanil and fuco xanthon so the answer should be having zanil and fuco xanthin so the answer is here as uh most of you answered it as
Option A and B so the right answer is here amount of xano and fuco xanthin option D I think it is correctly answered by Rashi option d f so option D A and B both is a right answer option D A and B both is a right answer next question choose the correct
About cell of brown Al Brown Al C cell cover outside algen cellulosic cell wall with pectin and polysulfate eers they have two filla equal size and laterally inserted A and C both option D A and C both what is your response guys yes the first quick answer is given by B GAA
Okay I’m sorry okay what about others yes YouTube students Aishwarya Shivam morti answered it as option b Rashmi answered it as option D fine Priya answered it as option D so see here cell wall covered by algen a gelatinous coating so cell wall will be algen and inside will be cellulose so
Like that the answer should come inside will be cellulose and outside will be a algen so cellulosic uh cell wall cover outside by algen so option A as quickly and correctly answered by B GAA so option A is a right answer guys option A is a right answer next
Question diota is a member of dict example so it is a member of same member of ectocarpus gelidium and fcus same member of those having cineria or manitol as stored foot same member of laminaria porir and fucus same member those having spico arthin as accessory
Pigment dicta is a member of yes my dear YouTube students Sanjay answered it from YouTube okay then anyone from YouTube dicta is a member of yes YouTube students any guesses here no answers from YouTube yes what about here very simple question you have to remember the examples okay the first
Quick answer is given by B GAA as option b an okay what about others yes YouTube students no answer from YouTube okay diota is a member of be fast aishwaria answered as option b b GAA answered as option b so before you should know that that this diota is a
Brown Alig guys it is a brown Alig if it is a brown Al it should be having I mean the whatever the examples of brown Alto carpus porir sasm okay so these all are the examples of brown Alig so what is the option here what are the options given
Here as you can see same member those having cam area or manitol as stored foot same member those having Pico arrine as an accessary pigment that is wrong C is wrong a gelidium fucus that is wrong gelidium fucus jellium B so option b same member those having cameria or
Manol all the brown Al will store the food in the form of cineria or manitol right right so option b is a right answer option b is a right answer next question gamuts of sasm are yes YouTube students any doubts py form cup shaped ribbon shaped and discoid yes YouTube students gamuts of
Sasm who is going to answer first okay the first quick answer is given by B GAA okay fine yes YouTube students someone is answering like okay only B goai is answering what about others gamuts of sarcasm will be yes YouTube student student sjay from YouTube they’re asking indirectly the
Shape yes yes yes the shape they are not asking isog gamas an isog gamas and all any answers from YouTube no yes guys only B answered it okay I got one more from Rashmi Rashmi answered as cup shaped okay cup shaped h okay so the right answer is here guys
What happens no here the sasm gamuts will be peer shaped or P shaped the peer shaped is called as py form the peer shaped is called as py form so the right answer is here py form option A no option a py form is a right answer next question oh okay
Fine now let us discuss the other part after the Alig we have many other Concepts to be discussed yes so when we come to the plant classification we got to know that nonvascular plants in nonvascular plants we will get mosses liver oats or horn wordss where bopy pidy bopy will come Al
And bopy right so let us discuss regarding bopy bopy was coined remember please do listen the explanation because you have to answer the questions okay Brown bopy was coined by a scientist named Brown bow Sonia is the largest bopy bow Sonia its length is 40 to 50 cm very important guys
Bonia is a largest bopy zupus is a smallest bopy then we have certain genus in the Brites no genus Ria was named after PF brixie genus maren was named after n Marchant please take the screenshot otherwise scribbl down in your book Professor Shivam Kap is known as father
Of Indian biology he studied the Bri iyes which are found in India in detail with a depth knowledge so Professor Shivam Kash is known as he hails from India he is known as father of Indian biology any doubts YouTube students yeah okay fine next question brop fites are also called as
Amphibians of plan Kingdom because these can live in soil and dependent on water for their reproduction that is for certain period of life cycle they need water they usually occur in damp that is moisture humid and shaded localities they play an important role in succession sorry in plant succession on
Bare rocks and soil next succession continue they are continuing by growing on rocks and all so structure the plant body of bopy is more differentiated than that of alation because it was just made up of a flat like structure attached to something so it isal like prate or and it is attach to
Something it is called substratum it is attached to the substratum or the support by unicellular or multicellular rids the rids rids root like structure yes YouTube students any doubt rids root like structure Roots Allah root like structures they might be unicellular mul they lack true root stem and leaves
They may possess root like Leaf like stem like strcture but actual Roots leaves stem the main plant body of a is heid in nature so plant body heid a single set of chromosomes gamy dominant body G single set of chromosome next it produces gamuts hence
It is called gamy the sex organs in bopy brop these are multicellular in nature when we come to reproduction male sex or an female sex Ori male sex organ will produce bagate and thids male sex hormon sorry part male gate anid I female sex orap okay shap and produces
Single the anoid are released in water m g these are released in water and they will go and enter the aronium female reproductive part enter they will reproduce sexually they will come in contact with aronium and anoid fuses with the egg zy do not undergo reduction division zot will be deployed in
Nature deployed in nature sois reduction it produces a multicellular body produce which is called sporo sporo is not free living it will be attached to the photosynthe gor it will be attached to the parent that is gide and it derives the nutrients from the parent G condition the
Sporo some cells of the sporo undergo reduction division to produce hpid spores these spores germinate to produce gy spor only that group of cell will undergo and they produce germinate you will get again new brop or a g in a gtic condition so dominant part that is gam to produce
Spores to produce gy to continue the succession right so this is a just about bopes guys regarding economic importance and the classification we will study in the next session until that take take care have a nice day bye-bye
