Osmosis And Diffusion

Intro. 1.1-(1) spreading- Is the movement of atoms/ molecules in a random fashion, moving from a high ducking of water to a low denseness of water. Osmosis- Is simply the public exposure of water molecules from a high immersion of water to a low concentration of water by means of a semi-permeable membrane. : Process of Osmosis and diffusion. 1.2- Important factors affecting osmosis and diffusion would be how concentrated the resolving power or solute is, the temperature that the surroundings or the solution is. What your use and as well how grownup the particle is. 1.3-Aim: The arrive of the test is to inscription a rhubarb plant plant jail cell chthonian a microscope, using different concentrations of flavor-water solution to determine how a great ingest the cell decreases in size, volume and shape and to record the disparity in cell reduction. (2) 1.4-Hypothesis: This sample we expect that the rhubarb cells go away drastic eithery shrink with th e higher concentrations of salt-water solutions. 1.5-Before commencement this experiment we didnt know how drastically the rhubarb cell would shrink, or if this experiment would actually be a success. We learnt that Osmosis and Diffusion played a very important part to our experiment and we could also document at just how much the salt water concentrations abnormal the cells. 2. Experimental Method and Design. 2.1 Equipment: 3x 100ml Beakers.
