a plant pigment that absorbs sunlight
Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength a phenomenon known as fluorescence.

Sunlight is absorbed by chlorophyll a green pigment located in plant cell structures called chloroplasts.
. Chlorophyll is an extremely important biomolecule critical in photosynthesis which allows plants to absorb energy from light. Chloroplasts contain several structures each having specific functions. Chlorophylls job in a plant is to absorb lightusually sunlight. The sunlight as it penetrates water portions of spectrum such as red orange yellow and green light rays which are of short wavelengths are filtered out.
The green pigment chlorophyll cannot trap these light rays of great wavelength and the green plants are thus unable to carry. Chloroplasts are specialized organelles found in all higher plant cells. The energy absorbed from light is transferred to two kinds of energy-storing molecules. In plant cells its found in an organelle called a chloroplast.
Chloroplasts are the sites of photosynthesis. Through photosynthesis the plant uses the stored energy to convert carbon dioxide absorbed from the air and water into glucose a type of sugar. Water is obtained by the plant through the roots and delivered to the leaves through vascular plant tissue systems. The pigment molecule is called chlorophyll.
Chlorophyll also chlorophyl is a green pigment found in cyanobacteria and the chloroplasts of algae and plantsIts name is derived from the Greek words chloros green and phyllon leaf. Decreasing the duration of light decreasing the intensity of light increasing the amount of oxygen increasing the amount of. Plants use glucose together with nutrients taken from the soil to make. Only the blue and violet rays of greater wavelengths remain and penetrate to great depths.
If a pigment absorbs light energy one of three things will occur. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane as. Energy may trigger a chemical reaction as in photosynthesis. Hemoglobin and myoglobin are pigments found in humans and animals.
