Answer 2

(a) The four main parts of a flower are sepals,petals,androecium,gynoecium.

(b) Ovule(female gamete) is produced by ovary of the flower and Anther produces pollen grains (male gamete).

(c)Pollengrains from other plants fall on the sigma and reaches micropyle that opens the door to ovary where fertilization takes place.So many parts are involved in pollination of pollen grains.
