Plants store energy produced during photosynthesis primarily in the form of sugars, specifically glucose. During the photosynthesis process, chlorophyll in plant cells captures sunlight and uses that energy to convert carbon dioxide and water into glucose and oxygen. The glucose serves as an essential source of chemical energy that plants can utilize for growth, reproduction, and maintenance of their cellular functions.

Additionally, glucose can be converted into other forms of energy storage as needed. For instance, plants may convert glucose into starch, a polysaccharide, which serves as a longer-term energy reserve. This conversion allows the plant to store excess energy when conditions are favorable and utilize it when energy demands increase, such as during periods of rapid growth or adverse environmental conditions.

In contrast, while proteins, fats, and oxygen are also important substances in plants, they do not serve as the primary form of energy storage from photosynthesis. Proteins are vital for plant structure and function, fats are primarily involved in membrane structure and functionality, and oxygen is a byproduct of the photosynthesis process rather than a storage form of energy.
