Web29 nov. 2024 · The life cycle of pteridophytes is probably best exemplified by the general life cycle of the fern. Ferns have a life cycle that alternates from a mature adult to an immature fern. WebLife Cycle. As with all plants, lycophytes have two alternating generations. The dominant generation in lycophytes is the sporophyte generation which produces spores for reproduction. Multiple spores are developed in sporangia and dispersed by wind and water. If a spore finds a suitable habitat, it can grow into a gametophyte.
