➧Subkingdom Cryptogamae divided into three groups:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵
❶❫ Thallophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plants body remains in the form of Undifferentiated.
②❭ Vascular System is Absent.
③❭ Mode of nutrition is Phototrophic & Autotrophic.
④❭ Reproduction is both Sexual & Asexual.
⑤❭ Asexual reproduction takes place by Spore formation.
⑥❭ Fertilization is not followed by Embryo formation.
▶Ex:- Spirogyra, Ulva, Fucus, Volvax & Chara
❷❫ Bryophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plant body is not differentiated into true roots, steam & leaves.
②❭ Non-vascular plant are not developed.
③❭ Fixation by rhzoids.
④❭ Gametophyte are the main plant.
⑤❭ Sex organs are multicellular.
⑥❭ Water is required for fertilization.
▶Ex:- Funaria, Riccia, Notothylus, Marchantia & Sphagnum
❸❫ Pteridophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plant body is differentiated into true roots, steam & leaves.
②❭ Vascular plant are developed.
③❭ Fixation by roots.
④❭ Sporophyte are the main plant.
⑤❭ They are the first truly Terrestrial & vascular cryptogams.
⑥❭ Water is needed for fertilization.
▶Ex:- Azolla, Dryopteris, Marsilea, Equisetum & Selaginella
