Question

Choose the correct answer from the alternatives given.
Plants are green because they

• A. absorb only green wavelengths of light
• B. absorb only yellow and blue wavelengths of light
• C. reflect green wavelengths of light
• D. reflect yellow and blue wavelengths of light

Answer 1

The correct option is C reflect green wavelengths of light

Green plants are green because they contain a pigment called chlorophyll. 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 option is, reflect green wavelengths of light'.
