The result of a male gamete fertilizing a female gamete is a zygote.

The gametes are formed in the gonads, which also have hormonal functions. A gamete is a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

A motile gamete is a sperm cell; it is motile because it has a flagellum and it swims around, and it is a gamete because, combined with the non-motile ovum, it can form a zygote and hence a new organism.

The difference of these two male gamete's is that the animal gamete has purple micro fibres and the flower gamete has blue micro fibres. I hope this helps
