Which organ in angiosperms is responsible for the reproductive function of the plant?

Roots

Flower

Fruit

The answer is a flower.

Flowers are the reproductive structures of the plant. Usually, they contain both male and female structures. Reproduction occurs when pollen from an anther fertilizes the egg. Fertilized egg develops into the seeds while ovary develops into the fruit to protect the seeds. Roots are vegetative structures which absorb water and nutrients from the ground, support plants, and store food.
