Detailed explanation-1: -Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen. When breakdown of glucose occurs with the use of oxygen it is called aerobic respiration.
Detailed explanation-2: -Aerobic respiration process takes place in all multicellular organisms including animals, plants and other living organisms. During the respiration process in plants, the oxygen gas enters the plant cells through the stomata, which is found in the epidermis of leaves and stem of a plant.
Detailed explanation-3: -Plant cells do not have mitochondria and therefore cannot respire using aerobic respiration. Anaerobic respiration occurs in the cytoplasm, therefore plants do experience anaerobic respiration.
Detailed explanation-4: -The majority of plants and animals, including birds, humans and other mammals, use aerobic respiration. Anaerobic respiration is used by microscopic organisms such as bacteria and fungus.
Detailed explanation-5: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
