Question

Plants are green in colour because

• A. They absorb green light only.
• B. They reflect green light.
• C. They absorb green light but reflect all other lights.
• D. None of these.

Answer 1

The correct option is B They reflect green light.

• Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum.
• Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum.
• Greenlight is not absorbed but reflected, making the plant appear green.

So, the correct answer is option B.
