Question

Define the following term
1) Fertilization​

Answer 1

Answer:

During pollination, pollen grains are carried from the anther of a flower to the stigma of the same or some other flower of the same kind.

After pollination, pollen grain forms a tube (called pollen tube).

The pollen tube grows through the style and reaches one of the o vul e in the o va ry. The pollen tube enters the en tube ovule through a small opening called micropyle.

Pollen tube contains two male gam etes. One of the male gam ete s passes through the pollen tube and reaches the egg in the ovule. Here, it fuses with the egg and a z ygo te is formed. This fusion is called fertilisation.
