what is the relationship between osmosis and tonicity?
7798
Tonicity. The ability of an extracellular solution to make water move into or out of a cell by osmosis is know as its tonicity. A solution's tonicity is related to its osmolarity, which is the total concentration of all solutes in the solution.

Why osmotic pressure become abnormal. Osmotic pressure is a colligative property I.e. it depends upon number of particles of solute present in the solution. In case of solute which undergo association or dissociation, osmotic pressure is not normal ,it is more or less than the expected.

In biology, this is a difference between the two processes. One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

The osmotic pressure of a solution is the pressure difference needed to stop the flow of solvent across a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution.

No, it is not correct because it happens with other liquids (solvents) also. ... Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.

Osmosis is a type of passive transport, unlike active transport. Active transport utilizes the use of protein pumps such as sodium-potassium pumps, while osmosis does not. Another difference is how osmosis does not require any energy to move the molecules while active transport does.

What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane.

The relation between both is that the greater the number of solute particles contained in the solution, the greater the osmotic pressure. In effect, the osmotic pressure is ultimately exerting an influence on the other solution. The solutes can be small electrolytes or it can be protein molecules.

Osmolarity and tonicity are related but distinct concepts. ... The terms are different because osmolarity takes into account the total concentration of penetrating solutes and non-penetrating solutes, whereas tonicity takes into account the total concentration of non-freely penetrating solutes only.

Explanation: Simple diffusion is the movement of molecules from an area of higher concentration to lower concentration. ... Osmosis is the movement of water from an area of less concentration of dissolved particles to an area of high concentration, thus equalizing the concentrations on each side.

Both go down concentration gradient. Osmosis is the movement of water molecules, but diffusion is for any molecule. Osmosis happens across a partially permeable membrane, while diffusion does not need a membrane, it happens directly in the fluid.

Osmosis involves the movement of water molecules. Water molecules move from a region of high concentration to a region of low concentration. Facilitated diffusion on the other side involves insoluble compounds such as sugars, amino acids and ions which can pass through a partially permeable membrane.

During osmosis, fluid moves from areas of high water concentration to lower water concentration across a semi-permeable membrane until equilibrium. In dialysis, excess fluid moves from blood to the dialysate through a membrane until the fluid level is the same between blood and dialysate.

Osmolality is a variation of molality that takes into account only those solutes that contribute to a solution's osmotic pressure. It is measured in osmoles of the solute per kilogram of water. This unit can be determined simply from the depression of the freezing point of the solution.

Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane. A semipermeable membrane allows passage of water but not of solutes. The passage of water occurs because of a pressure difference of water between the two solutions.

Answer Expert Verified Correct answer: Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration.
