What Gametes are?

Biology course work help please

Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. In humans, male gametes are sperm and female gametes are ova (eggs). Sperm are motile and have a long, tail-like projection called a flagellum. Ova however, are non-motile and relatively large in comparison to the male gamete.
