Final answer:
Food energy is converted from light energy into chemical energy (glucose) during photosynthesis. The glucose is then broken down in the presence of oxygen during cellular respiration to release energy for the cell.
Step-by-step explanation:
During photosynthesis, food energy is converted from light energy into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells, where sunlight, water, and carbon dioxide are used to produce glucose and oxygen. The glucose can then be used by the plant for growth and energy.
During cellular respiration, the glucose produced during photosynthesis is broken down in the presence of oxygen to release energy. This energy is used by the cell to perform various functions, such as growth, repair, and movement. The end products of cellular respiration are carbon dioxide and water.
