Here's why:
* Photosynthesis produces glucose, a simple sugar.
* Glucose is a readily usable form of energy but is not ideal for long-term storage.
* Plants convert glucose into starch, a complex carbohydrate, which is a more stable and efficient way to store energy.
* Starch is stored in various plant parts, including roots, stems, leaves, and seeds.
