Chlorophyll

Explanation:

Chlorophyll an important class of pigments involved in photosynthesis. PHOTOSYNTHESIS is the process by which light energy is converted to chemical energy through the synthesis of organic compounds.

Chlorophyll is found in virtually all photosynthetic organisms, including green plants, prokaryotic blue-green algae, and eukaryotic algae. Chlorophyll absorbs energy from light; this energy is then used to convert carbon dioxide to carbohydrates.

Chlorophyll occurs in several distinct forms: chlorophylls A and B are the major types found in higher plants and green algae; chlorophylls C and D are found often with A in different algae; chlorophyll E is a rare type found in some golden algae; and bacterio-chlorophyll occurs in certain bacteria. Variations are due to minor modifications of certain side groups. Chlorophyll is similar in structure to hemoglobin (the oxygen-carrying pigment found in the red blood cells of mammals and other vertebrates).
