A mature male gamete smaller and more mobile than the female gamete gametes a haploid reproductive cell that can fuse with another haploid cell to form a zygote. Sperm is created in the testes, and it is a tiny cell that can propel itself with a long flagellum. The head of a sperm cell is covered in a layer called acrosome which consists of a number of enzymes which enable the. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. gametes are reproductive cells or sex cells that unite during sexual reproduction to form a new cell called a zygote. Male gametes are called sperm and female gametes are ova (eggs). Sperm are motile and have a long, tail-like projection called a flagellum. Ova are non-motile and relatively large in comparison to the male gamete. key difference male vs female gametes sexual reproduction is a form of reproduction which forms a new individual from a union of two types of gametes. A gamete is a mature haploid male or female germ cell which is capable of fusing with another germ cell of the opposite sex to form a zygote. Gametes vary in structure (anisogamete) and motility and are produced by different parents. A gamete is the male or female reproductive cell that contains half the genetic material of the organism. When two human gametes meet that is, a sperm cell and an ovum you get a zygote, a fertilized egg. Gametes mean mature haploid male or female germ cells able to unite with another (of the opposite sex) in sexual reproduction to produce a zygote. The long twisted tube where male gametes are stored while they mature.
