When Does Fertilization Occur in Flowering Plants

Question

When does fertilization occur in flowering plants?
A) Pollen grains land on the anthers of the female flower parts.
B) The female carpels and male anthers are united.
C) Sperm join with eggs inside the ovules.
D) Pollen joins with eggs inside the stigma.

Accepted Answer

Fertilization occurs when sperm join with eggs inside the ovules. This typically happens after pollen has landed on the stigma, grown a pollen tube down the style, and reached the ovules in the ovary. Once the sperm and eggs join, the fertilized egg develops into a seed, and the ovary develops into a fruit.
