What is heterospory? Describe how it has led to the evolution of seed habit in plants?

Heterospory is a significant reproductive strategy in plants where two types of spores, microspores and megaspores, are produced by different structures within the same plant. This contrasts with homospory, where a single type of spore is produced. Heterospory is a key evolutionary adaptation that has played a crucial role in the development of the seed habit in plants.

In heterosporous plants, microspores and megaspores give rise to male and female gametophytes, respectively. These gametophytes are small, multicellular structures that produce gametes (sperm and egg __________ ________ ___ ________ __________ __________.
