The movement of water/solvent across the osmotic gradient takes place in the presence of a semi-permeable membrane. It functionally depends upon the concentration of solute particles present on the both sides of the solutions which are separated by the semi-permeable membrane. In a cell where the concentration gradient is such that water tends to move inside the cell, the cell must be hypertonic with respect to the surroundings. Movement of water takes place across this concentration gradient from hypotonic to hypertonic solution (from surrounding to cell) until the osmotic concentration is same on both sides. In a plant cell, this movement will stop as early as the concentrations are same on both sides. On the contrary, the animal cells maintain a discrete physiological concentration of each and every ion inside the cell which is necessary for solute transport, intercellular communication, action potential and maintenance of electrochemical gradient. For this purpose, the animal cells have different kind of solute channel protien located in their membranes. Although osmotic gradient does play a role in solvent transport but maintenance of solute concentration is of primary importance and thus the general osmotic gradient is different in animal cells as compared to plant cells. In animal cells, it is more complex and sophisticated in nature and requires ATP for operation purpose.
