But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive in the human reproductive process, two kinds of sex cells, or gametes (pronounced: gah-meetz), are involved the male gamete, or sperm, and the female gamete, the. In sexual reproduction, which is often seen in fungi, plants, and animals, a small haploid gamete (male gamete, sperm in humans) and a large haploid gamete ( female gamete, ovum in humans) fuse together to form a diploid zygote (fertilized egg in humans)2 generally, males produce the small gametes, whereas females.
