Thallophyta_ plants that do not have well differentiated body design fall in this group.The plants in this group are commonly called algae.These plants are predominantly aquatic.Ex chara Spirogyra.
Bryophyta_These are called the amphibians of the plant Kingdom.The plant body is commonly differentiated to form stem and leaf like structure. However, there is no specialised tissue for the conduction of water and other substances from one part of the plant body to another. Ex Moss,Matchantia.
pteridophyta- In this group the plant body is differentiated into roots, stem and leaves and specialised tissue for the conduction of water and other substances from one part of the plant body to another. some Ex ferns and horse tails.
The thallophytes the brophytes and pteridophytes have naked embroys that are called spores. the reproductive organs of plant in all these three groups are inconspicuous and they are therefore called cryptogamae organs.

➧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
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
