Question

Chlorophyll appears green due to
A.Absorption of green light
B.Red fluorescence
C.Green fluorescence
D.Absorption of red and blue light

Answer 1

Hint: Chlorophyll is the green pigment present in the plants and also responsible for the green colour of the leaves. Due to the chlorophyll plants are able to perform the process of photosynthesis and prepare their own food in the presence of sunlight.

Complete answer:
1.Chlorophyll pigment is present in green plants and responsible for that green colour of leaves
2.As per the absorption spectrum the colour of anything is visible when it doesn’t absorb that same colour from the light spectrum instead of that it reflects that colour and simultaneously absorbs all other colours of the light spectrum.
3.As per the rule of light spectrum chlorophyll doesn’t absorb the green colour of the white light instead of that it reflects the green colour of the white light.
4.Here chlorophyll absorbs the red colour wavelength and also the blue colour wavelength but it reflects the green colour wavelength due to which the colour of chlorophyll is green and also the leaves of the plants also appear green in colour.
5.So from the above detail we can say that the chlorophyll appears green due to absorption of red and blue light from the light spectrum.
Hence the correct answer is OPTION(D)

Note: 1.Green plants have autotrophic mode of nutrition as they prepare their own food by the process of photosynthesis.
2.Here chlorophyll traps the sunlight and initiates the process of photosynthesis, so chlorophyll is the most important component for the process of photosynthesis.
