Fertilisation In Pollination

Question 1

Describe the process of fertilisation.

Answer 1

1. Digestive enzymes are produced by the tip of the pollen tube, enabling it to grow through the style and ovary tissues and reach the ovule.
2. The pollen grain enters the ovule through a small gap, the micropyle , to reach the egg cell (the female gamete).
3. The male nucleus/gamete is then able to travel down the pollen tube into the ovule, so that it can fuse with the egg cell (fertilisation).
