Question

Are horsetails homosporous or heterosporous?

Answer 1

Horsetails:

1. Horsetails (Equisetum) are pteridophytes belonging to the class Polypodiopsida. They are mostly found in damp and shady areas.
2. Heterosporous plants produce two kinds of spores- microspores and megaspores. Microspores and megaspores give rise to male and female gametophytes respectively.
3. Horsetails are homosporous. They produce only one kind of spore that develops into a bisexual gametophyte.
4. The bisexual gametophyte produces both male and female gametes.
