During the stage of photosynthesis referred to as the light-dependent reaction, 12 molecules of water begin the process of reacting with six molecules of carbon dioxide to produce one molecule of glucose, six molecules of oxygen and six molecules of water.
After carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. Respiration. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars.The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes.hotosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2).
