☆☆ Pteridophyta Characteristics ☆☆
》Pteridophytes are the first true land plants.
》They are seedless, vascular cryptogams.
》Life cycle is heterologous diplohaplontic type.
》Sporophyte has true roots, stem and leaves.
》Spores develop in sporangia are homosporous or heterosporous.
》Sporangia are produced in groups on sporophylls.
》Young leaves of sporophyte show circinate vernation.
》Sex organs multi-cellular and jacketed.

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.
