Answer 2

Explanation:

Androecium is known as the male part of a flower while gynoecium is the female part of a flower. In a bisexual or hermaphrodite flower, when androecium and gynoecium matures at different times, the phenomenon is referred as ‘Dichogamy’. It is nature's mechanism for avoiding self pollination and promoting cross pollination. Self pollination is the transfer of pollen grains from anther to stigma of the same flower or another flower of the same plant. Self pollination isn’t desirable because it doesn’t help in providing variations in the next generation.

Flower arrangement patterns (inflorescence) and other physiological barriers may affect the time at which the androecium and gynoecium mature in the same flower.

If the gynoecium matures early, this condition is known as protogyny

And if androecium matures early this condition is known as protandry.

Both protogyny and protandry leads to cross pollination.

Hope it helps you!!
