How does sugar get from the water to a celery leaf?

Answer 1

Sugar is transported from the water to a celery leaf through a process called transpiration and the plant's vascular system. Water, which contains dissolved sugars produced during photosynthesis in the leaves, moves up through the xylem vessels. As water evaporates from the leaf surface, it creates a negative pressure that pulls more water (and nutrients) upward. This movement helps deliver sugars from the leaves to other parts of the plant where they are needed for growth and energy.

Answer 2

Sugar in celery leaves primarily originates from photosynthesis, where plants convert sunlight, carbon dioxide, and water into glucose. Once produced in the leaves, this glucose is transported through the plant's vascular system, specifically the phloem, to various tissues, including roots and stems. While water is absorbed by the roots and transported through the xylem to the leaves, the sugar synthesized in the leaves does not come directly from the water; rather, it is created through the photosynthetic process using water and carbon dioxide.
