Question:

Alternation of generation is present in

Options:

1. Sea-pen
2. Sea-fan
3. Obelia
4. Sea anemone

Solution:

Alternation of generations is a type of life cycle in which an organism alternates between two distinct multicellular forms, typically a sexual reproductive form (gametophyte) and an asexual reproductive form (sporophyte). Obelia, a genus of hydrozoans (a class of cnidarians), exhibits alternation of generations in its life cycle. The polyp form of Obelia produces medusae (the sexual reproductive form) asexually through a process called strobilation, and the medusae release gametes for sexual reproduction. The medusae then develop into polyps, completing the alternation of generations. Sea-pens, sea-fans, and sea anemones, on the other hand, do not exhibit alternation of generations in their life cycles.
