Question

A heterosporous plant is one that:

• A. Produces a gametophyte that bears both sex organs.
• B. Produces microspores and megaspores giving rise to separate male and female gametophytes.
• C. Is a seedless vascular plant.
• D. Produces two kinds of spores, one asexually by mitosis and one by meiosis.

Answer 1

The correct option is B Produces microspores and megaspores giving rise to separate male and female gametophytes.

Heterosporous plants are the ones that produces two different type of spores. Spores can be different in shape and size and that's the name heterosporous.

It produces two different shaped spores to differentiate between male and female gametophytes. A male gametophyte is known as microspores and a small in size and female gametes are known as megaspores and are larger in size.

So, the correct option is 'produces microspores and megaspore giving rise to separate male and female gametophyte'
