Question

write fate of sepals after fertilisation.​

Answer 1

The flower has served its purpose after fertilization:

• Stamens, style, petals and stigma wither and typically fall off
• The calyx may either remain intact in a dried and shrivelled form or fall off
• The ovary enlarges to form the fruit, the ovarian wall forms the fruit wall. The ovary wall may either form a fleshy fruit wall or form a dry and hard fruit wall
• Ovules go on to become the seed

Answer 2

Explanation:

After fertilization the sepals, petals and stamens of the flower wither and fall off. The pistil however, remains attached to the plant. The zygote develops into the embryo and the ovules develop into the seed. The ovary develops into the fruit which develops a thick wail called pericarp that is protective in function.
