Question

Importance of heterospory?

Answer 1

Answer:

The zygote develops into the future sporophyte. The evolution of the seed habit is related to the retention of the megaspore. 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.

Answer 2

Answer:

.One of the most important advantages of heterospory is the formation of seed habitat. In homosporous plants, the male and female gametes are formed in the same prothallus. Thus the chance of fertilizing an egg with the sperm of the same prothallus is very high.
