Detailed explanation-3: -Once an ovule has been fertilised it will become a seed. To avoid competition (for light, water, etc.) with the parent plant the seed will be dispersed.

Detailed explanation-4: -Step one: After pollen has landed on the stigma, it grows a pollen tube down through the style to the ovary.
