Chlorophyll is a pigment which gives plants their green color and is found in most plants and algae. Chlorophyll also facilitates the process of photosynthesis which allows the absorption of energy from light. Isolation of Chlorophyll as a pigment by itself was first done in 1817 by French chemists Bienaimé Caventou and Joseph Pierre Joseph Pelletier.
Chlorophyll is green because it absorbs all the colors in the light spectrum except green. The highest amount of this pigment is found plant cells called Chloroplast. These cells are responsible for the photosynthesis function in plants. Chlorophyll and Chloroplast facilitate photosynthesis to subsequently aid the production of energy and Oxygen.
By absorbing sunlight, plants convert water and carbon dioxide to oxygen and energy with the help of Chlorophyll. This energy is used by the plant to sustain growth and development. Without it, plants would be unable to survive.
Since its discovery and isolation, there have been 6 different identified structures of the Chlorophyll molecule. They are Chlorophyll a, Chlorophyll b, Chlorophyll c1, Chlorophyll c2, Chlorophyll d and Chlorophyll f. Chlorophyll a is the most commonly occurring and found in plants. When the leaves of a plant suffer from Chlorophyll deficiency, they tend to turn yellow. This condition is known as Chlorosis.
