Plants store their excess carbohydrates in the form of starch?

Yes, plants store their excess carbohydrates primarily as starch, which is a polysaccharide made up of glucose units. Starch serves as an energy reserve that can be broken down into glucose when the plant needs energy for growth, reproduction, or other metabolic processes. This storage occurs mainly in organs such as roots, tubers, and seeds, allowing plants to survive periods of low photosynthesis or adverse environmental conditions.
