The products of photosynthesis which are important to humans are OXYGEN AND GLUCOSE. The main product of photosynthesis is GLUCOSE ,which is the molecule that produces energy to run the process of the cell.six molecules of carbondioxide and six molecules of water are needed to produce one molecule of glucose. During the process of photosynthesis,carbondioxide and water combines in the presence of sunlight and chlorophyll to produce carbohydrates and oxygen. Oxygen is essential for breathing in humans.
