Question

Assertion :Photomodulation of flowering is a phytochrome regulated process. Reason: Active form of phytochrome $\left(P_{fr}\right)$ directly induces floral induction in shoot buds.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

Photomodulation of flowering is a phytochrome regulated process. In short day plant, inactive form of phytochrome (P${}_r$) induces the floral induction in shoot buds. However, in long day plants, active form of phytochromoe (P${}_{fr}$) induces the floral induction in shoot buds. Therefore, the assertion is true, but the reason is false.

Thus, the correct answer is option C.
