Q

What are the two kinds of pollination?

A

Self pollination and cross pollination

17
Q

What are the two types of pollination?

A

Wind and insect polliantion

18
Q

What is self pollination?

A

Transfer of pollen from anther to the stigma of the same flower or of different flower on the same plant

19
Q

What is the advantage of cross-pollination over self-pollination?

A

Cross pollination ensures the exchange of genetic materials from different plants and results in greater variation

20
Q

What is the advantage of self-pollination over cross-pollination?

A

If there are no pollinating insects and If plants of the same species are growing in isolation.
