Photosynthesis (Photo Synthesis).The photosynthesis process. Is a process that plants and organisms change light energy to come in the form of chemical energy in organic molecules is created. Energy in organic molecules. Be used as a source of energy in the life of plants and living things on the earth. The photosynthesis process, this may be considered to be only a single process of plants and organisms that can draw energy from the sun into the circulation in the world.Plants get light energy in any wayPlants and / or creatures with the photosynthesis process. Must have the ability to absorb light energy. The energy used to create bonds (chemical bond) in the molecules of organic compounds.Molecules capable of light absorption in plants and creatures is a pigment (pigment) pigment used in the photosynthesis process. (photosynthetic pigment) can be divided into 3 big categories. According to the characteristics of the structure of molecules, including1. Chlorophyll.A pigment found common in plants and creatures with the photosynthesis process. The structure consists of the porphyrin-like structure which has Mg2 + at central of the structure. And the long line of hydrocarbon, which is part of a hydrophobic region which embedded on the photosynthetic membrane in chloroplast2. Phycobilins.A pigment that is accessory light-harvesting pigments found in cyanobacteria and red algae. The structure is open-chain. Tetrapyrroles.Phycobilins associated with photosynthesis process that is known in general have 3 type is phycoerythrin (or phycoerythrobilin). Phycocyanin (or phycocyanobilin) and allophycocyanin (allophycocyanobilin) the three species are not found in higher plants, but found only in Cyanobacteria and red algae.3. Carotenoids.The pigment with a yellow - orange. Commonly found in plants and creatures can be synthesized by light. Obligation to help get the light energy accessory light-harvesting pigment to photosynthesis. And served in protection from light (photoprotective agents).Group with a yellow - orange pigment Commonly found in plants and creatures can be synthesized with light duty.
