What happens if the plant does not use its sugars immediately during photosynthesis?

If a plant does not use its sugars immediately during photosynthesis, it can store the excess sugars in the form of starch or convert them into other compounds like cellulose for structural support. This stored energy can be utilized later when the plant needs it, particularly during periods of low light or when photosynthesis is not occurring, such as at night. Additionally, the stored sugars can be used for growth, reproduction, and energy during times of stress.
