Life Cycle Of Pteridophytes . The main generation is the sporophyte, which is the dominant phase. This means that a plant must complete two distinct generations in order to complete its life cycle.

Pteridophytes have a dependence on water. The life cycle of the fern has two different stages; Sporophyte, which releases spores, and gametophyte, which releases gametes. The body of the sporophyte is well differentiated into roots, stem and leaves.

The root system is always adventitious. The life cycle of pteridophytes is a continuous reproductive process that is dominated by the sporophyte (sexual) stage of the alternation of generations. Reproduction and fusion of gametes can happen in the presence of water. The heterosporous pteridophytes represent the highest stage of development in the second or intermediate series of plants. The life.
