Question

Which one of the following is not the role of phytochrome?

• A. To induce curvature in plants on light application
• B. To increase the amount of chlorophyll
• C. To induce flowering
• D. To induce germination

Answer 1

The correct option is A To induce curvature in plants on light application

Phytochrome is a photoreceptor, a pigment that plants use to detect light. It is sensitive to light in the red and far-red region of the visible spectrum. If seeds sense light using the phytochrome system, they will germinate. Phytochrome does not induce curvature in plants on light application. It is called as phototropism.
