write to differences between diffusion and osmosis
Answers
Explanation:
when people discuss osmosis in biology it always refers to the movement of water one big difference between osmosis and diffusion is that both slovent and solute particles are free to move in diffusion but in osmosis only the slovent molecules (water molecules ) Cross the membrane
Answer:
Diffusion is defined as the process of movement of substances from a region of higher concentration to a region of lower concentration across the membrane.
Example : If we add a drop of ink in water , it diffuses with the rest of water and colours it. Similarly, the fragrance of a burning incense stick placed in a corner of the room spreads in the whole room due to diffusion in air.
Osmosis is defined as the process of movement of solvent particles from a region of their high concentration to that of low concentration across a semi–permeable membrane.
Example : In case of sugar solution, plasma membrane is permeable to water molecules, but impermeable to smaller to large sugar molecules.
In other words ,osmosis occurs in the direction of higher solute concentration and lower solvent concentration.
