Here's why:
* Photosynthesis is the process where plants, algae, and some bacteria use sunlight, water, and carbon dioxide to create their own food.
* This food is in the form of glucose, a simple sugar.
* Glucose is a high-energy molecule that can be used directly by the plant or stored for later use.
* Plants can store glucose as starch, a more complex carbohydrate, for long-term energy storage.
