1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.

As a result of stress the adenohypophysis releases _ACTH_, which stimulates release of hormones from the adrenal cortex that retain sodium and water (aldosterone), increase blood sugar (cortisol), and begin breaking down fats.
ACTH = AdrenoCorticoTropic Hormone
