Question
Fern prothallus is monoecious. Justify.
✓

Answer

  1. Ferns are homosporous and hence produce only one kind of spores.
  2. Each spore germinates into a prothallus, the gametophytic stage.
  3. The male and female sex organs, antheridia and archegonia, are borne on the same prothallus and hence fern prothallus is monoecious.
