Cellular Respiration
Plants and animals get the food they need in different ways. Plants use the energy in sunlight to produce food in the form of glucose. Animals eat other organisms for food. To release the energy in food, the cells in plants and animals need to break down the glucose through a process called cellular respiration.
Cellular respiration takes place in the mitchondria of cells. During cellular respiration, oxygen interacts with glucose which causes chemical changes that give off energy. The energy is used to power the cell. Carbon dioxide and water are produced as waste products. Plants can use the waste products for photosynthesis. Animals release the waste products into the air when they exhale.
