    The Effect of Osmosis on a Potato Cell October 12th 2012 Osmosis Lab Purpose: The purpose of this lab is to investigate the effects of osmosis on a potato cell as it is immersed for a period of time in solutions of different water concentrations. Hypothesis: If the potato is immersed into the distilled water‚ then it will be the heaviest out of the three. This is because water is at the lower is moving toward the area of higher concentration‚ which in this case is the potato. This

    Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

    distilled water Apparatus : A Visking tube‚ cotton thread‚ test tubes‚ beaker and water bath Procedure - Soak the Visking tube in water for 5 minutes to soften it. Open the Visking tube and tie one end of the tube with cotton thread to prevent leakage. - Fill the Visking tube with 15ml of glucose solution and 15ml of starch suspension. Tie the other end of tube tightly with cotton thread. Record the colour of the solution - Rinse the outer surface of Visking tube with distilled water. - Mix

    The Measurement of the Rate of Osmosis by using “Deshelled” Chicken Eggs (Effect of Solute Concentration upon Rate/Degree of Osmosis in Chicken Eggs) Introduction Every cell needs a mechanism that it uses in the maintenance of a constant internal environment. This is important in the control of the ever changing external environment to the cell. The transfer of materials to and from the cell thus needs a very stable mechanism to achieve this status. Cells are therefore bound a membrane that acts

    Introduction Osmosis is the movement of water from a region of higher concentration ( hypertonic ) to a region of lower concentration ( hypotonic solution ) through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion called “ passive transport “ which means no energy is required. Diffusion is the movement of a substance by which the molecules move from a region of higher concentration to a region of lower concentration. Aim

    he mass and length of the potato piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length

    Osmosis Practical Report Introduction: To determine the biological changes that occur to potato cores over a period of time in different solutions of sucrose and to relate these changes to the phenomenon of osmosis. Method: We soaked several discs of potato cuted using a cork borer with around 1 centimeter of diameter and 2 milimeters of lenght into sucrose solutions with a different range of concentrations from 0 to 1.0M. Then we weighed all the potato

    I am going to investigate osmosis when potato is placed in different  concentrations of sucrose. I am aiming to witness osmosis in 5  different concentrations of sucrose. I will use 5 varying  concentrations so that I have a wider spread to compare the results‚  and check that I don’t have any anomalies  Prediction  Osmosis is the process of diffusion of water molecules from a weaker  solution into a stronger solution‚ through a semi permeable membrane.  The tiny pores in the membrane
