Effect of different types of domestic detergents on Membrane Permeability of Beta vulgaris Cells

Effect of different types of domestic detergents on Membrane Permeability of Beta vulgaris Cells Research question. To investigate how the effect of different types of domestic detergents has on membrane permeability of hands skin cells using the similarity of effect on Beta vulgaris cells. Hypothesis. By exposing a cell membrane to a detergent it will increase permeability. Stronger is the detergent more permeable will be the membrane it will destroy the cell membrane. By similarity, the permeability of the Beta vulgaris cell membrane is disrupted causing the red pigment to leak out by diffusion. If the detergent damage the beet cell membrane there will be a higher percentage of pigment leakage and so it has less transmission percentage transmission of light than distilled water. Type of variables. Representing variables in this experiment. Dependent variable. Color of the detergent change. Independent variable. Constituents of detergent and kinds of detergent. Control variable. Temperature of detergent used and the surrounding. The volume of detergent used. Time for the reaction Probe calibration the same probe between measurements to ensure that the measurements are all consistent Background information. Cells have a selectively permeable membrane that allows selective substances to penetrate into the cell.
