Vedclass · Answer

(A) The evolution of sexual reproduction,ranging from isogamy to anisogamy and finally oogamy,is best illustrated by the green algae (Chlorophyceae). In this group,we observe a clear progression: $1$. Isogamy: Fusion of morphologically similar gametes (e.g.,$Chlamydomonas$). $2$. Anisogamy: Fusion of morphologically dissimilar gametes (e.g.,$Eudorina$). $3$. Oogamy: Fusion of a large,non-motile female gamete and a small,motile male gamete (e.g.,$Volvox$,$Spirogyra$ showing conjugation).
