Photosynthesis

Photosynthesis is a process taken into action by autotroph organisms in order to produce their own energy supplies. Autotrophs, such as plants and algae are capable of utilizing several elements oftheir environments to synthesize food supplies, they require sunlight as the main fuel for all of these processes, with it being the primordial energy source for all living beings, next come otherfactors such as temperature and humidity.
Photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthetic organismsare called photoautotrophs, since they can create their own food. In plants, algae, and cyanobacteria, photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesisis vital for all aerobic life on Earth. As well as maintaining the normal level of oxygen in the atmosphere, nearly all life either depends on it directly as a source of energy, or indirectly as theultimate source of the energy in their food.
As well as energy, photosynthesis is also the source of the carbon in all the organic compounds within organisms bodies.
Even if photosynthesis canhappen in different ways in different species, some features are always the same. For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reactioncenters that contain chlorophylls. In plants, these proteins are held inside organelles called chloroplasts, while in bacteria they are embedded in the plasma membrane. Some of the light energy gatheredby chlorophylls is stored in the form of adenosine triphosphate. The rest of the energy is used to remove electronsfrom a substance such as water. These electrons are then used in the reactions thatturn carbon dioxide into organic compounds. In plants, algae and cyanobacteria, this is done by a sequence of reactions called the Calvin cycle. Many photosynthetic organisms have adaptations that...
