  • Osmosis is the diffusion of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The process occurs without any expenditure of cellular energy and continues until equilibrium has been reached (i.e., when solute concentrations are equal on both sides of the membrane).
  • In this article, you will get CBSE Class 9 Science notes on chapter 5 'Is The Fundamental Unit of Life' (Part-II). These chapter notes are prepared by the subject experts and Main topics covered in this part of CBSE Class 9 Science, The Fundamental Unit of Life: Chapter Notes, are: Diffusion. Osmosis.
  • Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Diffusion Versus Osmosis

  • The diffusion model of osmosis is rendered untenable by the fact that osmosis can drive water across a membrane toward a higher concentration of water. The "bound water" model is refuted by the fact that osmosis is independent of the size of the solute molecules—a colligative property [14] —or how hydrophilic they are.

  • Dec 01, 2011 · This means that osmosis must of happened because the 2 mixtures reached equilibrium. But another thing also happened during this experiment. Some of the glucose in the bag crossed the membrane, entering the mixture in the cup, which also helped it reach equilibrium. In conclusion, this experiment was a great example of osmosis and diffusion.

  • Abstract A diffusive model of osmosis is presented that explains currently available experimental data. It makes predictions that distinguish it from the traditional convective flow model of osmosis, some of which have already been confirmed experimentally and others have yet to be tested.
