    And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells. In experiment

    example of diffusion is red food coloring. When you put food coloring in a glass of water the color will spread through the water until all of it is a red tint. This shows the molecules of the food coloring equally distributed in the area of the water. Osmosis is a special type of diffusion where only the water molecules move. This happens through a selectively permeable membrane. It allows water and oxygen to move freely across the membrane. Osmosis only has an effect when the cell is in a hypotonic or

    according to Campbell et al. (1999)‚ water is the major constituent of cells. Reactions vital to life occur under aqueous conditions in the body and cells of all organisms‚ and the concentrations of reactants necessary for these reactions depend upon the amount of water present (Pough et al. 2004). By the process of osmosis‚ water moves from areas of lower to areas higher concentration across a water- permeable membrane‚ like a cell membrane (Nybakken and Bertness 2005). In order to maintain the proper

Make any corrections in blue so I know what to re-read Osmosis Diffusion is the net movement of particles from an area of high concentration to an area of low concentration. Then what is osmosis? Basically‚ osmosis is the same action with diffusion but in water. To describe more precisely‚ osmosis is the net movement in water across partially permeable membrane‚ which mean the membrane allows
