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.
photosynthesis is the process where plants take oxygen/co2 from the air and water from the ground and use the sunlight shining on their leaves mixed with the water and air to create glucose, a type of sugar that they live on.
Phenotypic bacterial identification relies on isolating the sample and observing for biochemical reactions, such as, the ability to ferment sugars and hydrolyze various substrates.
