Cellular respiration is the process of synthesizing cellular energy (ATP) from organic sources such as water, glucose and oxygen. These substances are processed through a series of steps in order to produce ATP. The main organelle responsible for ATP synthesis is the mitochondria.
In plants, the photosynthetic pigment, chlorophyll, is found within chloroplasts. The process of photosynthesis is driven by light and carbon dioxide from the environment, converting these into glucose, water and energy.
