The process of transforming the chemical energy of cellular fuels into the high energy bonds of ATP in plants is called respiration. During respiration, organic molecules such as glucose are broken down in the presence of oxygen to release energy. This energy is then used to make ATP, which is the main source of energy for all cellular activities in plants. In contrast, photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen. This glucose can then be used in respiration to produce ATP. Photolysis is a process of splitting water molecules into oxygen and hydrogen ions, which occurs during photosynthesis. Autotrophism is a characteristic of organisms that can produce their own food, such as plants, through processes like photosynthesis. Therefore, while photosynthesis and autotrophism are important processes for plants to produce their own food, respiration is the process by which plants use this food to produce ATP and provide energy for all cellular processes.
