Question

write down the characteristics of plants belonging to division pteridophyta​

Answer 1

Important characteristic Pteridophyta

1. Members of this group are most primitive living vascular plants.

2. The main plant body is a sporophyte. It is differentiated into root, stem and leaves.

3. Plants (sporophyte) reproduce by spores formed in sporangia. Sporangia develop either on the ventral surface or in the axil of leaves.

4. Plants may be homsoporous or heterosporous. The development of sporangium may be of eusporangiate (when develop from group of initials) or leptosporangiate. (When develop from a single initial) type.

5. Spores develop into a multi-cellular gametophytic body called prothallus - a thalloid structure. It is independent and chlorophyllous. It bears male reproductive organs called antheridia and female reproductive organs called archegonia. Reproductive organs are multi cellular and jacketed.
