Question

What we concluded from pollen and stigma study biology?

Answer 1

Answer:

pollen grain is carrier of male gametes and stigma

is the recipient of the pollen grains which helps in the germination of pollen tubes by providing nutrients for the pollen grains.

Answer 2

The study of pollen morphology and stigma surface ornamentation with the help of LM and SEM concluded that the apertural characters, surface pattern, exine ornamentation, size and shape of the pollen grains and the surface pattern of the stigmas play an important role in successful pollination of selected taxa.
