Question

differnce between diffusion and osmosis​

Answer 1

Explanation:

• Diffusion can occur in any mixture, including one that includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.
• When people discuss osmosis in biology, it always refers to the movement of water. In chemistry, it's possible for other solvents to be involved. 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. This can be confusing because while the solvent particles are moving from higher to lower solvent concentration across the membrane, they are moving from lower to higher solute concentration, or from a more dilute solution to a region of more concentrated solution. This occurs naturally because the system seeks balance or equilibrium. If the solute particles can't cross a barrier, the only way to equalize concentration on both sides of the membrane is for the solvent particles to move in.

Answer 2

Answer:

The spontaneous movement of a substance (solid, liquid, gas) from a region of its higher concentration to a region of its lower concentration is called diffusion. The movement of water molecules through a semi permeable membrane along a concentration gradient is called osmosis.
