The chlorophyll aborbs green wavelengths of light.

|
The chlorophyll aborbs blue and yellow wavelengths which make green.
|
|
|
Chlorphyll reflects the green wavelengh of light.

|
|
Green is an optical illusion caused by the transmission of Refracted light.

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. Plants that use photosynthesis to make their own food are called autotrophs.
Detailed explanation-2: -So, plants and their leaves look green because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell. The unused green light is reflected from the leaf and we see that light.
Detailed explanation-3: -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-4: -All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Accessory photosynthetic pigments, including chlorophyll b and beta-carotene, absorb energy that chlorophyll a does not absorb.
Detailed explanation-5: -Chlorophyll. The green pigment in leaves is chlorophyll, which absorbs red and blue light from sunlight. Therefore, the light the leaves reflect is diminished in red and blue and appears green.
