Why is photosynthesis considered the most important chemical process on earth? Photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, andâ¦ many species of bacteria. In plants, algae and cyanobacteria photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesis is vital for life on Earth.
Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds. This process consists of a series of chemical reactions that require carbon dioxide (CO 2) and water (H 2 O) and store chemical energy in the form of sugar.Light energy from light drives the reactions.Oxygen (O 2) is a byproduct of photosynthesis and is released into the atmosphere.hotosynthesis transfers electrons from water to energy-poor CO 2 molecules, forming energy-rich sugar molecules. This electron transfer is an example of an oxidation-reduction process: the water is oxidized (loses electrons) and the CO 2 is reduced (gains electrons).
