Green plants reflect ____ light.
A
Red
B
Green
C
All
D
Red and Violet
Explanation: 

Detailed explanation-1: -Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Detailed explanation-2: -Sometimes one may hear that plants don’t use green light for photosynthesis, they reflect it. However, this is only partly true. While most plants reflect more green than any other in the visible spectrum, a relatively small percentage of green light is transmitted through or reflected by the leaves.

Detailed explanation-3: -Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us.

Detailed explanation-4: -As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.

Detailed explanation-5: -Green light is not absorbed but reflected, making the plant appear green.
