What does the direction of sugar transport vary from season to season?

The direction of sugar transport in plants varies from season to season primarily due to changes in photosynthesis and energy demands. During the growing season, sugars are produced in the leaves and transported to growing tissues (like roots and fruits) for growth and development. In contrast, during the dormancy of winter, stored sugars are transported from roots and stems back to the leaves to maintain metabolic functions. This seasonal shift helps plants optimize energy use and support growth cycles.
