Detailed explanation-1: -Final answer: Heterospory is considered important in the development of Seed Habit.

Detailed explanation-2: –Heterospory is thus considered an important step in evolution as it is a precursor to the seed habit.-Heterospory evolved first in pteridophytes such as Selaginella and Salvinia.-The seed habit is the most complex and evolutionary successful method of sexual reproduction.-It is found in vascular plants.

Detailed explanation-3: -The term heterosporous describes plants that produce many spore types that vary in shape, size, and function. They produce tiny microspores and larger megaspores, two different types of spores. The majority of pteridophytes are homosporous, which means they only produce spores of the same sort.

Detailed explanation-4: -Heterospory is advantageous in that having two different types of spores increases the likeliness that plants would successfully produce offspring. Heterosporous spores can respond independently to selection by ecological conditions in order to strengthen male and female reproductive function.

Detailed explanation-5: -Seed habit is considered as the adaptation of heterospory and retention and germination of single megaspore within a megasporangium. It is considered as the most advanced and successful method of sexual reproduction adopted by terrestrial plant mostly.
