Answer 2

$\huge\bf{Answer :}$

Soon after the act of double fertilization, the flower starts losing its luster. The petals, stamens, and style either fall off or wither. However, the calyx, however, may persist in some cases, i.e., tomato, bringal. The major changes happen -

• ★ Development of endosperm.
• ★ Development of fetus.
• ★ Development of seeds.
• ★ Development of fruits.

Development of endosperm:

The development of the endosperm precedes the development of the embryo and the cells of the endosperm provide nutrition to the growing embryo.

Development of Embryo:

The zygote divides by mitosis and forms the prombrio. This leads to cotyledon as a result of the formation of mature embryos.

Development of Seed:

The fertilized egg is called the seed that is the end product of sexual reproduction. It consists of seed coat, cotyledon and a fetal sac.

Development of fruits:

The ovary develops into a fruit and the ovary wall develops into a wall covering the fruit.
