Question

Assertion : Algae show only anisogamous type of reproduction.
Reason : In algae, gametes can never be non flagellated.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

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 (nonmotile) but similar in size (as in Spirogyra). Such reproduction is called isogamous.
