Detailed explanation-1: -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. Black pigments absorb all wavelengths of visible light that strike them.

Detailed explanation-2: -Chlorophyll is a molecule in chloroplasts that absorbs some of the energy in visible light. Energy from sunlight is absorbed and transferred along the thylakoid membrane. Water molecules are broken down and all oxygen is released.

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: -What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.

Detailed explanation-5: -Chlorophyll a is the most abundant pigment in plants. Chlorophyll a absorbs light mostly 430nm (blue) and 662nm (red) wavelength light. It reflects green light so it appears green to us. Chlorophyll b molecule has a similar structure to that of chlorophyll a.
