Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the fuel used by all living things.Photosynthesis takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.Photosynthesis is the chemical change which happens in the leaves of green plants.Light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plant cells and algae. Absorbed light energy is used to convert carbon dioxide and water into a sugar called glucose.We are going to provide Photosynthesis Practice Test Online Question Answer over here in order to prepare yourself with respect to such significant topic of Biology as well.Just Click on the given below quiz in order to start your preparation online and get instant result accordingly.
