Question

Which of the following is heterosporous?
A) Whisk fern
B) Spike moss
C) Horsetail

Accepted Answer

Spike mosses are heterosporous, meaning they produce two types of spores: microspores and megaspores, which develop into male and female gametophytes, respectively. This is a characteristic feature of some vascular plants, including spike mosses (Selaginella), distinguishing them from the others listed, which are homosporous.
