Bryophytes typically measure one to two centimeters tall. They lack tissues to provide structure and support that other land plants have, so they cannot grow taller. Instead, bryophytes grow close together into a cushion-like covering over soil, rocks, tree trunks, and leaves.
Though they require water for hydration as well as reproduction, they are able to survive on land because of special adaptations. Bryophytes are covered in a waxy cuticle that helps them to retain water. As water flows through an area, it is absorbed by bryophytes. Bryophytes hold on to water like a sponge, helping creatures who depend on water for survival as well as reducing flooding in an area.

➧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
