Classify the following into osmosis Into diffusen ? (A) Preserving pickles in salt (b) aquatic animals using oxygen dissolved in water during respiration
Answers
The movement of particles from low concentration to high concentration is responsible for the diffusion in liquids and gases. In the case of osmosis the particles move from the low concentration to high concentration through the semi permeable membrane, this happens because of diffusion.
Hence, osmosis is called a special kind of diffusion.
