Human<unk>  The<unk> , or ovum (plural ova), is the female reproductive<unk> , or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile). If the male gamete (sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized the oosphere becomes the oospore. When<unk>  and sperm fuse during fertilisation, a diploid<unk>  (the zygote) is formed, which rapidly grows into a new organism.
