Zygote is a diploid cell because it receives one set of chromosomes from the female gamete and one set of chromosomes from the male gamete
Male gametes, sperm cells, are produced in the testes. During sexual intercourse sperm cells travel through the sperm duct, into the urethra and released out the end of the penis
Female gametes, egg cells, are produced in the ovaries. Eggs are released from the ovaries into the oviducts
If an egg is fertilised, it divides a number of times then implants into the wall of the uterus where it grows and develops into a new individual
The head of a sperm cell has a nucleus and a cell membrane, there is a midpiece containing mitochrondria and a tail

Numerous rounds of mitotic cell division takes place. Many of the new cells become specialised to perform particular functions
