Here's why:
* Starch is a complex carbohydrate made up of many glucose molecules linked together. Plants produce starch as a way to store excess glucose that they create through photosynthesis.
* Starch granules are found within plant cells, particularly in storage organs like roots, tubers, and seeds.
* When the plant needs energy, it breaks down the starch molecules into glucose, which can be used for growth, reproduction, and other cellular processes.
While other carbohydrates exist in plants, starch is the primary long-term energy storage molecule.
