Question

define fertilisation and describe it process in detail...in plants​

Answer 1

Explanation:

✷Plant fertilization is the joining of male and female gametes, resulting in a zygote. ✷The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization. ✷After fertilization, the zygote divides to form an embryo.

Answer 2

Explanation:

After pollination pollen grains forms a tube (called pollen tube).

The pollen tube growa through the style and reaches one of the ovule in the ovary. The pollen tube enters the ovule through a small opening called micropyle.

Pollen tube contains two male gametes passes through the pollen tube and reaches the egg in the ovule. Here, fuses with the egg and a zygote is formed. This fusion is called fertilisation.
