Question

Mention the changes a flower undergoes after fertilisation.

Answer 1

1. The outer layers of the ovule become impervious and hard and function as a seed coat. An ovule with an embryo inside is called a seed.
2. The ovary enlarges and ripens to become a fruit. Other floral parts such as sepals, petals, stamens, styles, and stigma may fall off. However, in some cases, they remain persistent in the fruit.
