Answer:
After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem. Once water leaves the xylem, it moves across the bundle sheath cells surrounding the veins.1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.Plant water uptake, or transpiration, represents the process by which water in soil is drawn into plants and returned in gaseous form to the atmosphere through leaf stomata.Water transport also occurs at the cellular level, as individual cells absorb and release water, and pass it along to neighboring cells. Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane.Most of the water that a plant takes in enters through the root hairs.
