Hint:The leaves are the integral part of a plant which is capable of performing photosynthesis. The leaf contains pigment chlorophyll which is green in colour whose main function is to absorb the sunlight.
Complete answer:
To answer this question, we must know about the colour of the leaves due to reflection.
Plants contain different pigments with different colours. The green pigment called chlorophyll is the main photosynthetic pigment which absorbs light. There are two types of chlorophyll present in plants i.e, chlorophyll A and B. They can absorb light from 400-650nm. Chlorophyll A is the main pigment which takes part in the electron transport chain whereas chlorophyll B is the accessory pigment.
Chlorophyll A is the most abundant pigment present in plants. It absorbs the light of wavelength blue (430nm) and red (662nm). It does not absorb green whose wavelength is 550nm.
The plants absorb all the wavelength of visible light except green which it reflects. Thus due to the reflection of green colour, the leaves on the plant appear green.
Additional Information:Human eye can see the colour present in the white light that falls in the wavelength 380-750nm. Out of it, violet has the highest frequency.
Note:The wavelength of 400 and 520 nanometer is best absorbed by chlorophyll. This range falls for violet-blue light. The photosynthesis cannot take place in the artificial light as the artificial light does not mimic the spectrum and energy of sunlight.
