Solution

The correct option is D Both a and b
Events that occur after fertilisation are called post-fertilisation events.

In angiosperms the post-fertilisation events include:

1. Embryogeny (Development of embryo from zygote).
2. Formation of endosperm to provide nutrition to the developing embryo.
3. Maturation of ovary into fruit.
4. Maturation of ovule into seed.

Porogamy is the entry of pollen tube into the ovule through micropyle. It occurs before fertilisation.
