(B) In $Chlorophyceae$ (green algae),sexual reproduction shows considerable variation in the type and formation of sex cells.It may be isogamous,anisogamous,or oogamous.$1$. Isogamous: Fusion of morphologically similar gametes (e.g.,$Ulothrix$).$2$. Anisogamous: Fusion of morphologically dissimilar gametes (e.g.,$Eudorina$).$3$. Oogamous: Fusion of a large non-motile female gamete and a small motile male gamete (e.g.,$Volvox$,$Spirogyra$ is an exception as it is isogamous but non-motile).Therefore,all three types of sexual reproduction are observed in $Chlorophyceae$.
