Solution

The correct option is D Both Assertion and Reason are incorrect

Sexual reproduction in algae takes place through fusion of two gametes. These gametes can be flagellated and similar in size (as in Chlamydomonas) or non-flagellated (non-motile) but similar in size (as in Spirogyra). Such reproduction is called isogamous. Fusion of two gametes dissimilar in size, as in some species of Chlamydomonas is termed as anisogamous. Fusion between one large, non-motiie (static) female gamete and a smaller, motile male gamete is termed oogamous. So, the correct answer is 'Both Assertion and Reason are incorrect'.
