WATER RELATIONS IN PLANT AND ANIMAL CELLS

WATER RELATIONS IN PLANT AND ANIMAL CELLS The medium (solution) surrounding cells or organisms is described by the terms hypotonic, hypertonic and isotonic. A solution whose solute concentration is more than that of the cell sap is said to be hypertonic A cell placed in such a solution loses water to the surroundings by osmosis A solution whose solute concentration is less than that of the cell sap is said to be hypotonic A cell placed in such solution gains water from the surroundings by osmosis A solution which has the same solute concentration as the cell sap is said to be isotonic When a cell is placed in such a solution there will be no net movement of water either into or out of the cell   Osmotic Pressure               The term osmotic pressure describes the tendency of the solution with a high solute concentration to draw water into itself… Read More »WATER RELATIONS IN PLANT AND ANIMAL CELLS
