Question

What's the difference between pollination and fertilization?

Answer 1

Pollination only occurs with flowers. It is when pollen spreads from the male part of the flower to the female part of the flower. Fertilization only occurs with animals. Fertilization is when the sperm (from the male) attaches to the egg (in the female) which forms a zygote. 

Answer 2

Firstly, pollination is the transfer of pollen from the anther (male organ of the flower) to the stigma (female organ of the flower) of the same or different flower. Secondly, fertilization occurs once the pollen grain reaches the stigma, it produces a pollen tube, which grows down through the style to the ovary.
