Question

Select the heterosporous fern from the following:

• A. Salvinia
• B. Pleris
• C. Lygodium
• D. Angiopleris

Answer 1

Answer:

A. Salvinia

• Plants that produce spores have varied structures, sizes, and functions.

• They generate two types of spores: microspores and megaspores.

• Most pteridophytes are homosporous, meaning they generate just one type of spore.

• Salvinia is a heterosporous pteridophyte because it produces two types of spores: microspores and megaspores.

• Microspores are small spores that give rise to male gametophytes following germination, whereas megaspores are big spores that give rise to the female gametophyte.
