describe how cell respiration photosynthesis and cell reproduction
Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules. Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.Animals obtain food molecules from plants and other organisms, and then undergo cellular respiration to obtain ATP molecules. Cellular respiration occurs at all times. â Photosynthesis involves conversion of one type of energy into another: light energy into chemical energy. â Cellular respiration involves using that chemical energy and breaking it down to release energy.
1 Photosynthesis â The process of capturing light energy and converting it to sugar energy, in the presence of chlorophyll using carbon dioxide and water. 2  Respiration â The process of metabolizing (burning) sugars to yield energy for growth, reproduction, and other life processes.n photosynthesis, the plant uses water and nutrients from the soil, and carbon dioxide from the air with the sunâs energy to create photosynthates. Oxygen is releases as a byproduct. Figure 2.
