Answer:

Step-by-step explanation:

Plants store glucose in the form of starch. Starch is a complex carbohydrate made up of many glucose molecules linked together. It serves as a storage form of glucose in plants and is found in various parts of the plant, such as roots, stems, and seeds.

Starch is synthesized in the chloroplasts of plant cells through a process called photosynthesis. During photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose. Some of this glucose is used immediately for energy, while the excess is converted into starch and stored for later use.

Starch is an efficient way for plants to store glucose because it is insoluble in water and can be compactly packed within plant cells. When the plant needs energy, enzymes called amylases break down the starch into individual glucose molecules, which can then be used for cellular respiration and other metabolic processes.

Unlike animals, plants do not store glucose as glycogen. Glycogen is the storage form of glucose in animals, particularly in the liver and muscles. Plants also do not store glucose as fructose or maltose, as these are simple sugars that are typically used for immediate energy production rather than long-term storage.

To summarize, plants store glucose in the form of starch, which is a complex carbohydrate made up of many glucose molecules linked together. Starch serves as an energy reserve in plants and is found in various parts of the plant, such as roots, stems, and seeds.
