Question

What happens to the following after fertilization?
(a) Ovules
(b) Calyx
(c) Petals
(d) Stamens

Answer 1

• Ovules —

1. Ovules become the seed post fertilization.
2. After fertilization occurs, each ovule develops into a seed.
3. Each seed contains a tiny, undeveloped plant called an embryo.
4. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.

• Calyx —

1. After fertilization, the calyx sheds or falls off or remains intact in a shriveled and dried form.
2. After fertilization, most of the time, the calyx falls as its purpose of protection of the flower and its reproductive parts is over.
3. If the calyx does not fall off, it dries or becomes wrinkled and shrunken by staying intact. Hence, petals also shed and fall off.

• Petals —

1. Post fertilization, the petals shed and fall.
2. Petals are the most colourfull or brightly coloured part of a flower and they play an essential role by attracting pollinators for pollination and protect the ovary.
3. Thus once after the fertilization, petals fall off.
   

• Stamens — Once fertilization takes place, the stamens fall off.
