Sperm develops before pollination.

* self pollination happen when....... * i dont know
seeds develop by needing these parts the embrayo,seed coat and the endosperm
cross pollination
pollination hapins.
Pollination is required for flowering plants to reproduce. This is due to the pollen acting as the sperm for the plant, and the pollen has to enter the ovum of the plant to create the seeds.
Pollination is the spreading of pollen from the male to the female part of a flower. Fertilization is the sperm and egg joining to form a zygote and occurs in animals.
A sperm or egg alone can not develop into a new individual. Only an egg fertilized by a sperm does.
The flower is to attract insects and bees, etc, and aid in cross-pollination for seeds to develop. If cross-pollination doesn't take place, there will still be a flower, but no seeds will develop.
The Correct Answer Is Cross-Pollination Save
Pollination is required for flowering plants to reproduce. This is due to the pollen acting as the sperm for the plant, and the pollen has to enter the ovum of the plant to create the seeds.
Before
After flowers wither, the flower will become a fruit because of pollination.
