Question

Selaginella has a character of evolutionary importance, which is presence of?

• A. Seed
• B. Heterospory
• C. Strobilus
• D. Rhizophore

Answer 1

The correct option is B Heterospory

Because Selaginella has both microspores and megaspores, the plant is called as heterosporous. The other fern-allies are homosporous (having only one type/size of spore). This significance of this advance in evolution is important because sexual dimorphism is being expressed much earlier in the life cycle. The organisms to appeared next this are all heterosporous.

Therefore, the correct answer is option B.
