Answer 2

$\huge\mathbb{ANSWER}}$

Changes in a flower after fertilisation : 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. The ovary enlarges and ripens to become a fruit. Other floral parts such as sepals, petals, stamens, styles and stigma may fall off.
