Solution

The correct option is D
Cell membrane

Cell membrane

Water passes from a region of high water concentration or the surrounding wet soil through a semi-permeable membrane or the cell membrane to a region of lower water concentration in the cytoplasm. At any point of time, the water may be diffusing into the cells from outside following its own concentration gradient. So if the external solution has a higher water potential than the cell sap, the water enters displacing the solute molecules outside the cell.

Absorption of minerals by the epidermal cells of root and root hair causes the water to enter from surrounding soil into roots. It further reaches the root xylem. Thus, due to a continuous uptake of water by root cells, a water pressure is created in the root xylem. This pressure is called as________
