Assertion (A): Syngamy in Plasmodium is anisogamy
Reason (R): The gametes are similar in size The correct answer is: Assertion (A) and Reason (R) are correct, but (R) is not the correct explanation of (A).
- Assertion (A) is correct as syngamy in Plasmodium involves anisogamy, which is a form of sexual reproduction involving gametes of different sizes or forms, typically male and female gametes.
- Reason (R) is incorrect because it states that the gametes are similar in size, which contradicts the definition of anisogamy. In Plasmodium, the male and female gametes differ significantly in size, with male gametes being smaller and more mobile.
- Thus, while the assertion correctly describes anisogamy, the reason incorrectly describes the characteristics of gametes in Plasmodium, making it an inaccurate explanation of the assertion.
