WebThe general term osmose, now osmosis, was introduced in 1854 by a British chemist, Thomas Graham. (Britannica, n.d). This lab shows the rate of osmosis between three different concentrated cells and their outer environment. The dialysis tube mimicked the purpose of a cell membrane and the water in the beaker acted Webout of the cell depending on the concentration gradients. However, the cell membrane is not permeable to larger non-lipid molecules, as a result these molecules can’t diffuse into and out of the cell unless specifically transported by a carrier mechanism. Osmosis. is the diffusion of water, and it occurs across a semi-permeable membrane in ...
