Q

What are the steps in pollination?

A

Step one: After pollen has landed on the stigma, it grows a pollen tube down through the style to the ovary.
Step two: The nucleus of the pollen grain travels down the pollen tube and fertilises the nucleus in the ovule.
Step three: The fertilised ovule develops into a seed.
