Question

Quizplus · Accepted Answer

Water is absorbed from the soil by the root hairs and transported to the leaf cells via the xylem vessels. This water is then used for photosynthesis in the leaf mesophyll. While some water vapor may enter the leaf through the stomata, it is not enough to sustain photosynthesis on its own. The phloem is responsible for the transport of sugars and other compounds produced during photosynthesis, but not water.
