Two ways in which pollination may occur in plants are:

1. Self-pollination

2. Cross-pollination

The three agents of pollination are:

1. wind
2. water
3. insects

The two features of flowers which favour pollination by insects are:

1. These flowers are large with coloured petals, to attract insects.
2. These contain nectar as food for insects.

False fruit is the one which develops from any other part except ovary.

eg. strawberry.
