    The Movement of Water and Solutes in Plants During the process of osmosis, water molecules move from an area that is hypotonic to an area that is hypertonic. A hypotonic area is one in which has less solute and a hypertonic area is one which has more solute. Plant cells, such as the ones in the epidermis and cortex regions of the roots of the plant, all have living contents, which are enclosed by a cell surface membrane and a thick, quite inelastic cellulose cell wall. The cell wall

    The Solute Concentration of a Potato To find out what the solute concentration of a potato is, this shall be done by finding out the effect of Osmosis on a potato. Prediction: That if there is more water outside the potato than inside, the potato will increase in size. If however there is less water outside the potato than within, then I shall expect the potato to shrink in size. I think this because of the laws of Osmosis. Osmosis is the diffusion of water through a partially permeable

    The Effect of Solute Concentration on Osmosis in Potatoes AIM: to find out the effect of solute concentration on osmosis in potatoes. This is to find the equivalent osmotic potential. [IMAGE] PREDICTION: Osmosis is the movement of water particles from a high concentration to a low concentration through a partially permeable membrane. Osmosis happens when a partially permeable membrane allows small water particles to pass in or out towards a low water concentration. To reach an equivalent

    The Effect of Solute Concentration on the Rate of Osmosis Aim: To test and observe how the concentration gradient between a potato and water & sugar solution will affect the rate of osmosis. Introduction: Osmosis is defined as, diffusion, or net movement, of free water molecules from high to low concentration through a semi-permeable membrane. When a substance, such as sugar (which we will be using in the experiment we are about to analyse), dissolves in water, it attracts free

    The Effect of Changing Solute Concentration on Osmosis in Potato Tissue Aim The aim of the investigation is to find out the effect of changing solute concentration on osmosis in potato tissue. Prediction I predict that if the solute solution is more concentrated than the potato, the potato chip with the more water potential will lose water, so if the potato chip is placed into a dilute solute solution, the potato will gain water. Here's the example- if the original cells is 5g then

    Investigate the Cell Sap Concentration of Solute in a Potato Chip using Osmosis Aim The aim of the experiment is to investigate the cell sap concentration of solute in a potato chip using osmosis and produce a figure informed by the investigation as to what this is. Background Information A factor that effects how much water moves into a cell is the solute concentration within it. Water moves in and out of cells by diffusion, this diffusion is called osmosis. Osmosis is the diffusion of water

    molecules from a region of their high concentration to a region of their low concentration through a partially permeable membrane. It is best regarded as a form of diffusion in which only water molecules move. For example look at Figure 2. The solute molecules are too large to pass through the pores in the membrane, so the movement of water molecules can only achieve equilibrium. Solution A has the higher concentration of water; so there will be a net movement of water from A to B by osmosis

    potential of the external solution will be equal to the water potential of the cell. (Roberts 1991) By convention, the water potential of pure water is set at zero. Knowing that solutes make the water potential of solutions lower, solutes make solutions negative. Solute potential is the amount that the solutes lower the water potential of a solution. Pressure potential is especially important in plant cells. If a plant, for example the potato tuber cells, is placed in pure water (or a

    The formula of solubility is: SOLUBILITY(g/100g)= (SOLUTE / SOLVENT) * 100 I did an experiment to prove this and find the solubility of potassium chlorate, an ionic solid. Apparatus: 2g potassium chlorates, some distilled water, a stand, a clamp, two beakers, a thermometer, a test tube, and a measuring cylinder. Method: 1. Put the potassium chlorate into the test tube, and then put 4g distilled water. 2. Then the solute (which is the salt) dissolves in water (the solvent)

    being pure, had a water potential of 0kpa. The potato cells have a lower Y due to molecules of solute inside the potato cells. This imbalance leads to movement of water from the solution into the potato cells in an effort to reach an equilibrium. This diagram below gives a basic visual representation of the process of osmosis when the potato chip is placed in pure water. [IMAGE] Solute molecule [IMAGE] [IMAGE] [IMAGE] Water flows form the area of higher Y, the
