➧Subkingdom Cryptogamae divided into three groups:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵

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.

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.
