How many pollen grains enter the ovary during pollination. If only one pollen tube enters,one seed should be formed.But how is it possible to form large nuber of seeds in a single ovary?

I guess fertilization can occur many times within one plant. Some flowers might have several ovules. Each ovule contains one ovum. When pollen grains land on the stigma, more than one pollen tubes can be formed and each carries a male gamete to one ovule.
