Best Answer

Pollen needs to be able to be spread far and wide in order for the flowering plant species to both spread and remain robust. By being tiny and prickly, pollen particles can be carried on the wind, or become attached to the legs and bodies of pollinating insects such as bees, ants and flies.

How many pollen grains are deposited into the female flower?

as many that stick to the stamen. it differs from plant to plant and it also depends on how many pollen grains stick to the insect that carries it. though once the pollen grain comes into contact with the stamen a pollen tube is created to reach the ovary. then two "sperm" come from this tube and one fertalizes the egg and one become the endosperm for nutrients for the egg/seed


If there is no female flower can the male flower turn into a fruit why?

The stamen in the flowers (the little things that poke out of the middle of the petals) have pollen on them and when bees come along they collect that pollen and as they fly along to different plants and flowers it drops the pollen which is what fertilizes the flowers.
