    • 7 Pages

    effects the rate of Osmosis in Artificial Cells. During our biology lab we learned all about cells, and to further our understanding we even conducted an experiment with an artificial cell. To start the lesson, we learned the difference between diffusion and osmosis, how concentration gradients affect both. Also how the cell membrane works, how tonicity affects plant and animal cells differently, how dialysis tubing works, and how it acts like a living cell. By the end of the lesson we…

    Research Question What is the effect of surface area on volume ratio over rate of diffusion of pigment regarding the agar cube, measure by percentage volume of diffusion through time? Hypothesis The experiment involves the use of agar cubes. If the cells of these cubes desire a great surface area to volume ratio in order to carry out their needs (exchanging materials with the environment, receiving oxygen, getting rid of waste products), the SA:V ratio will be larger. Consequently, the rate of…

    Potato Osmosis Experiment

    • 610 Words
    • 3 Pages

    Osmosis is the diffusion of water molecules from a region of higher concentration to a lower concentration of water molecules (through a partially permeable membrane). If the cell is placed in a higher water potential, water enters by osmosis and if the cell is placed in lower water potential, then the water leaves the cell by osmosis. The experiment we did shows the process of osmosis. How osmosis really works. That is, what will happen to the potato if it is being put in pure water and what…
