Detailed explanation-1: -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-2: -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-4: -Absorption spectra of the chlorophyll a and b pigments in the visible light range, measured in a solvent. Both types barely absorb green light. Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light.

Detailed explanation-5: -The colours of visible light form a colour wheel. Within that wheel the colour an object appears to be is the colour complementary to the one it most strongly absorbs. As such, plants look green because they absorb red light most efficiently and the green light is reflected.
