cortex cells

xylem

cortex cells

Explanation:
Detailed explanation-1: -Water moves through the root hairs of the epidermal cells through the cortex, including the endodermis, before entering the outermost layer of the vascular cylinder, the pericycle. the vascular cylinder (stele). Water ultimately enters the conducting cells of the xylem.
Detailed explanation-2: -Water is passively transported into the roots and then into the xylem via cells of cortex. Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The forces of cohesion and adhesion cause the water molecules to form a column in the xylem.
