Glucose, the primary product of photosynthesis, is a sugar formed from carbon dioxide and water molecules that acts as the primary food source for green plants. A secondary product of the process, oxygen, is released into the atmosphere as waste.
The process of photosynthesis involves absorbing light energy from the sun and converting that into chemical energy that the plant can use to break molecular bonds and create glucose molecules. Molecules called chlorophyll, which are found in all the green areas of the plant, enable it to capture solar energy. The energy harvested by the chlorophyll combines with water from the soil and carbon dioxide from the air to form glucose molecules.
