Lab Report: Diffusion and Osmosis| Process, results and reflection| | | | Julia| 01-Oct-11| |   Lab re trampe: Diffusion and Osmosis Diffusion is the movement of particles from an area of higher assiduousness to an area of lower minginess. Diffusion results because of the random movement of particles. The dispersal of wet into and out of a selectively permeable create from raw stuff layer is called osmosis. Because of the selectively permeable tissue layer, nothing but piddle and other very small particles can be cushy by osmosis. The prison mobile phone membrane is similar to the membrane mentioned above, so the cell would lose water because of osmosis if it were rigid in an environment in which water concentration is greater than that of the cell. A dissolver is isosmotic if the concentration of change state substances is the alike as the concentration inward the cell. Osmosis does not occur in an isotonic answer. A hypotonic solution is a solution in which the concentration of fade out substances is lower than the concentration inner the cell. If a cell were put in a hypotonic solution, osmosis will cause water to move through the cell membrane into the cell. A solution is hypertonic if its concentration of dissolved substances is greater than the concentration inside the cell.

If a cell were placed in a hypertonic solution, it would lose water. All particles that devour through the plasma membrane by the process of diffusion do not withdraw energy, so their movement is called peaceful transport. The transport of materials against a concentrati on gradient requires energy, so it is called! active transport. The purpose of this experiment was to throw observations and conclusions about the ability of cells to compensate to varying chemical concentrations in the environment and to observe the issuing of isotonic, hypotonic and hypertonic solutions on cells.
