Question

Write down the differences between diffusion and osmosis

Answer 1

Diffusion: The intermingling of one substance into another.
Osmosis: The passage of solvent molecules through a semi permeable membrane from a low concentrated to a high concentrated.

QUESTION -

Write down the difference between diffusion and osmosis ?

DIFFUSION

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

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.
