Most ova are unicellular because they are only one cell at first but becomes multi cellular once fertilized by the sperm and begin dividing. However, in other organisms, such as protists, they can start off as multi cellular as well. The ova is the female gamete produced by the female reproductive system and joins together with the sperm, the male gamete, during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set of chromosomes. Ova are produced by many living organisms, such as animals, protists, fungi, and flowering plants and ferns. In animals, they are produced…
