Explanation:
Photosynthesis is a process performed by autotrophic organisms like green plants. It is a phenomenon whereby these plants manufacture their own food (sugars) using an inorganic carbon source in the presence of sunlight to provide energy.
The major end product of photosynthesis is glucose, which has a carbon constituent i.e. C6H12O6. However, this carbon needed to make glucose is got from an inorganic molecule called CARBON DIOXIDE, which the plants take from the atmosphere in via the stomata on their leaves.
