Vedclass · Answer

(A) The Assertion is correct because phytochrome is a photoreceptor pigment that regulates various developmental processes,including flowering,in response to light.The Reason is also correct. Phytochrome exists in two interconvertible forms: $P_R$ (inactive) and $P_{FR}$ (active). When exposed to red light,$P_R$ is converted to $P_{FR}$. The $P_{FR}$ form is the physiologically active form that migrates to the nucleus or interacts with signaling pathways to induce floral development in shoot buds.Since the active form $P_{FR}$ is the specific component of the phytochrome system that triggers the flowering response,the Reason correctly explains the Assertion.

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