Sexual reproduction takes place through fusion of two gametes. These gametes can be flagellated and similar in size (as inUlothrix) or non-flagellated (non-motile) but similar in size (as inSpirogyra). Such reproduction is called isogamous. Fusion of two gametes dissimilar in size, as in species ofEudorinais termed as anisogamous. Fusion between one large, nonmotile (static) female gamete and a smaller, motile male gamete is termed oogamous, e.g.,Volvox, Fucus.
