  1. Isogamous is a type of sexual reproduction where male and female gametes are similar in size, e.g. in Spirogyra and Ulothrix.
  2. Anisogamy refers to a type of sexual reproduction in which two dissimilar gametes unite or fuse. The gametes may differ in size or form. Example : human beings, the male gamete sperm is smaller and motile while the female gamete egg is non motile and larger.
  3. When sexual reproduction involves the fusion of one larger non-motile female gamete and a smaller motile male gamete, it is called oogamous. E.g. Volvox, Fucus.
