Answer 1

In plants, fertilization can take place only after the pollen lands on the stigma of a flower.

• It is through pollination that the process of fertilization occurs in a flowering plant.
• The process of pollination occurs when the pollen land on the stigma of a flower.
• The sperm in the pollen then fertilized the egg present in the ovary of a stigma.
• Hence, the landing of a pollen on the stigma is necessary for the process of pollination to occur.

Answer 2

Explanation:

Only after pollination, when pollen has landed on the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds. A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary.
