Plants store carbohydrates for future metabolic use in the form of

Cellulose is a structural polysaccharide that forms the cell walls of plants, providing rigidity and support. While it is derived from glucose, it is not used for energy storage. Instead, cellulose serves a different purpose in maintaining plant structure and is not metabolized by most organisms, including humans.

Fats, or lipids, are not the primary storage form of carbohydrates in plants; they are instead used for storing energy in animals. While some plants do store energy in the form of oils or fats, the main carbohydrate storage in plants is starch, which is specifically geared towards future metabolic use.

Chlorophyll is a pigment crucial for photosynthesis, allowing plants to capture sunlight and convert it into chemical energy. It does not serve as a storage form of carbohydrates; rather, it plays a role in the process of energy conversion, which is distinct from energy storage.
