Question

Assertion (A): The ability of the pistil to recognise the pollen is the result of a continuous dialogue between pollen and pistil.

Reason (R): This electrical dialogue allows only compatible pollen to germinate.

Options

  • Both A and R are true and R is not the correct explanation of A.

  • A is true but R is false.

  • A is false but R is true.

Solution

A is true but R is false.

Explanation:

Assertion (A) is true because pollen recognition occurs through a continuous chemical interaction between the pollen and the pistil’s tissues, which helps determine compatibility.

Reason (R) is false because this interaction is chemical, not electrical.

Hence, the assertion is correct, but the reason does not support it.
