A seasonal plant flowers and sets Page 1/5. A significant step in the life cycle of flowering plants. In algae and bryophytes the somatic or vegetative plant body is a gametophyte which is dominant and visible. Like all vascular plants, their life cycle is dominated by the sporophyte generation. We call this a life cycle. Watch the recordings here on Youtube! Life Cycle of Gymnosperms. The ability to reproduce both sexually and asexually gives plants the flexibility to adapt to changing environments. Alternation of generations is of two types- isomorphic and heteromorphy.
