-
Most plants are green in colour because
-
- the atmosphere filters out all the colours of the visible light spectrum except green
- green light is the most effective wavelength region of the visible spectrum in sunlight for photosynthesis
- chlorophyll is least effective in absorbing green light
- green light allows maximum photosynthesis
Correct Option: C
The leaves appear green because of the pigment chlorophyll which does not absorb green light rather reflects it back.
