Question

a seed (heterosporous: referring to a plant species that has two kinds of spores: microspores, which develop into male gametophytes, and megaspores, which develop into female gametophytes)

Answer 1

In seed plants, there are two types of spores: microspores and megaspores, which develop into male and female gametophytes respectively. This reproductive strategy is known as heterospory.

Step-by-step explanation:

In seed plants, there are two types of spores: microspores and megaspores. Microspores develop into male gametophytes, while megaspores develop into female gametophytes. This reproductive strategy is known as heterospory. Seed plants, including all spermatophytes, are heterosporous, while lower vascular plants are mostly homosporous, producing only one type of spore.
