How does the process of water absorption occur in plants?

Water absorption in plants occurs through the roots, where specialized structures called root hairs increase the surface area for absorption. The process involves osmosis, where water moves from an area of high concentration in the soil to an area of low concentration in the root cells. This movement is facilitated by the presence of aquaporins, proteins that act as channels for water to pass through the cell membrane. Once inside the root cells, water is transported through the plant via the xylem vessels to reach the rest of the plant for various physiological functions.
