Solution:
Thallophytes are the simplest of plants meaning that the plant body is not differentiated into root, stem and leaves. Plants may be unicellular or multicellular. They may be green due to the presence of chlorophyll (Chlamydomonas, volvox, spirogyra and ulothrix) or non-green due to the absence of chlorophyll. (Mushroom, yeast and mucor).

➧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
