Question
How does the process of fertilisation take place in flowers?
✓
Answer
The process in which the male gamete fuses with female gamete to form a new cell (i.e. zygote) is called fertilisation.
The process of fertilisation in plants is as follows
(i) When the pollen is deposited on the stigma of the pistil, it begins to germinate. After some time, a long pollen tube is developed from the pollen grain which passes through the style towards the female gametes in the ovary.
(ii) The male gametes move down the pollen tube and the tube enters the ovule present inside the ovary.
(iii) The tip of pollen tube bursts and the male gamete comes out of the pollen tube. Inside the ovary, the male gametes fuse with the female gametes present in the ovule to form a fertilised egg cell which is called zygote.
(iv) The zygote develops into an embryo which is a part of a seed that develops into a new plant.
