    Question

    Alternation of generation occur in ______________.

    1. Bryophytes

    2. Bryophytes

    3. Algae

    4. All of the above

    Hint:

    Aquatic plants and nonvascular plants show alternation of generation.

    The correct answer is:

    All of the above

      Bryophytes are non-vascular plants. In their life cycle, they are the only embryonic plants (embryo-producing plants) whose life history includes a dominant (haploid) gametophyte stage. The alternation of generations is a life cycle consisting of two life phases that alternate regularly. In bryophytes, the first stage is the gametophyte stage,
      Alternation of generations occurs in almost all multicellular red and green algae, both freshwater types (such as Cladophora) and algae (such as Ulva). For the most part, generations are homomorphic (isomorphic) and live freely.
