Osmosis osmosis is a kind of diffusion which only occurs with water with osmosis, there is a membrane which does not allow dissolved material to pass though it but only water (selectively permeable) osmosis is the movement of water molecules from a weak solution to a strong solution.

This conclusion proves that water diffusion occurs from a hypotonic solution to a hypertonic solution osmosis in a plant cell was tested by comparing an elodea cell in pond, distilled, and salt water. Part b: osmosis six strips of 30 centimeter presoaked dialysis tube were obtained for each strip, an terminal was tied and approximately 25 milliliter of different solutions ( distilled h2o, 02 m saccharose, 04 m saccharose, 06 m saccharose, 08 m saccharose and 10 m saccharose ) was poured into their single bags. Osmosis is the diffusion of water down its concentration gradient normally one thinks of water as the solvent, and focuses on the concentration of the solutes, but water itself has a.
When two solutions having a different concentration from each other are separated by a semi-permeable membrane, acts on osmosis there occurs a net displacement of water in the solution with the lowest concentration in the solution with the highest concentration. Osmosis is a special case of diffusion the biochemical process in living cells always takes place in a solution a solution is made up of a solvent (the dissolving fluid) and solute (the particles dissolved in the solvent.
