Question

2. With the help of a diagram explain how pollination leads to fertilization.
​

Answer 1

Explanation:

The transfer of pollen grains from the anther to the stigma of a flower is called pollination. Pollination is of two type – Self Pollination and Cross Pollination. After pollination a thin tube called the pollen tube grows down from the pollen grain through the pistil. The pollen tube carries the male cell. It grows until it reaches the ovule and enters it. the male cell moves into the ovule and fuses with the egg to form the zygote which further develops into embryo.

Answer 2

Answer:

Only after pollination, when pollen has landed on the stigma of a suitable flower of the same species, can a chain of events happen that ends in the making of seeds.

The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant.
