• A. Isogamous, anisogamous, oogamous, isogamous, oogamous
• B. Anisogamous, isogamous, oogamous, isogamous, oogamous
• C. Oogamous, anisogamous, isogamous, isogamous, anisogamous
• D. Isogamous, anisogamous, oogamous, anisogamous, isogamous

Answer 1

The correct option is A Isogamous, anisogamous, oogamous, isogamous, oogamous

Sexual reproduction is the process of the fusion of two gametes. The gametes that undergo fusion can be flagellated and similar in size (as in Ulothrix) or non-flagellated (non-motile) but similar in size (as in Spirogyra). This type of reproduction is called isogamous. The fusion of two gametes that are dissimilar in size, as in the species of Eudorina, is known as anisogamous. Oogamous reproduction occurs when a large, non-motile (static) female gamete fuses with a smaller, motile male gamete, e.g., Volvox, Fucus.
