Question

What is the fate of the calyx and corolla after fertilisation

Answer 1

After fertilization, the flower petals wither, and the ovary containing the seeds becomes the fruit.

Answer 2

After fertilization, the following changes are observed in a flower:

There is formation of a diploid zygote and it develops into an embryo, which forms the future plant.

The endosperm cells serve as a source of nutrition for the developing embryo.

The ovule becomes the seed.

The ovary becomes the fruit.

In most of the plants the antipodals and synnergids disintegrate before, during or immediately after fertilization.

The outer and inner integuments of the ovule become the testa or the seed coat of the seed.

Petals and sepals fall off.
