What are the two forms in which plants store carbohydrates?

Plants primarily store carbohydrates in the form of starch and sucrose. Starch is a polysaccharide made up of glucose units and serves as the main energy reserve in roots and tubers. Sucrose, a disaccharide composed of glucose and fructose, functions as a transport form of carbohydrates throughout the plant. Both forms are vital for the plant's energy needs and growth.
