What is Photosynthesis

Context: Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs, "light", and synthesis, "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called Photoautotroph. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Answer: Photosynthesis is a process performed by different species where energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores.
