Mrs Tilschers Class

The Effect of Glucose Concentration on the Rate of Osmosis Aims In this investigating Ill be working to know: How does the intentness of glucose vector sum affect the respect of osmosis in spud chips? Why does the tightness of glucose solution affect the rate of osmosis in potato chips? How does the plenty of potato chips changes in different concentration glucose solutions? Introduction The occasion of this investigation is to observe the factors that affect the rate of osmosis in potato chips and check out the pretendment of osmosis done the cells of potato. Diffusion Diffusion is the plunder movement of particles from a component of high-pitched concentration to a region of first base concentration until the concentrations are equal. The speed of diffusion depends n the disagreements amongst the concentrations to begin with. Osmosis is a special part of diffusion, it occurs across a permeable membrane which allows some particles to mobilise through it and go along others. Therefore osmosis is the passage of weewee from a region of high concentration to a region of low concentration through a semi-permeable membrane.

The direction and the rate of osmosis depend on the difference in body of realise concentration between the two sides of the membrane and this movement forget continue until equilibrium is reached. Cell membranes will allow scurvy molecules like oxygen or peeing or coulomb dioxide or glucose to pass through to a greater extentover they will embarrass larger molecules like sucrose or starch or protein to pass throu gh. The tendency of water to move through a! partially permeable membrane is exposit as its water potentiality and is at a supreme in arrant(a) water. As solutes are added the water potential lowers and this means that more concentrated solutions read lower water potentials than more stretchiness solutions and so the water will have a greater tendency to move from pure water to any aqueous solution and from a more dilute solution to a more concentrated solution.
