    Investigating the Effects of Sucrose Concentration on Osmosis in Potato Tissue PLANNING ======== We have been asked to research the effects of sucrose concentration on osmosis in potato tissue. Osmosis is the spontaneous movement of a solvent (-in this case water) from a place where its chemical potential is higher to another place where it is lower, through a semi-permeable membrane (-such as a cell membrane). A cell membrane lets smaller molecules such as water through but does

  • Lab Report Testing the Effects of Changing Surcrose Concentration on Osmosis in Plant Cells

    Lab Report Testing the Effects of Changing Surcrose Concentration on Osmosis in Plant Cells Aim To investigate the effects of changing the sucrose concentration on osmosis in plant cells. Plan Water passes into cells through a special type of diffusion called osmosis. Water molecules diffuse through the membrane from a weak solution into a strong solution until the concentration is the same on both sides. A membrane that allows only certain molecules to pass through is called a semi-permeable

  • Egg Albumen Experiment

    1251 Words  | 6 Pages

    Egg Albumen Experiment The purpose of this investigation is to establish which is the lowest concentration of Copper (II) Sulphate solution that will denature a sample of egg albumen (egg white) at room temperature. The base of the reaction is the globular protein (albumen) being denatured by a heavy metal (Copper (II)), the copper (II) reacts with the NH3 group causing it to denature, this means the proteins' secondary and tertiary structures are being altered and refolding into different

    Investigating the Effect of Different Concentrations of Sucrose Solutions on Potato Tiessue Planning For my GCSE biology coursework, I am going to conduct an investigation into the effect of different concentrations of sucrose solutions on potato tissue. Text Box: A measuring cylinder Apparatus =========================================== 18 test tubes [IMAGE][IMAGE] Text Box: 1M sucrose solution [IMAGE]A test tube rack [IMAGE] Cork borer Text Box:

  • Investigating the concentration of the solutions inside the vacuole of a potato cell.

    1461 Words  | 6 Pages

    Osmosis Investigation We are trying to find out what the concentration of the solutions is inside the vacuole of a potato cell. We will investigate how the mass of the potato chips change in different sucrose solution concentrations. We will use osmosis to do this. I will be measuring and controlling many different variables, these include; - The dependent Variable – Weight of potato chip Independent Variable – Concentration of sucrose Control Variables consist of; - 1.     Temperature

  • The Effect of Solute Concentration on Osmosis in Potatoes

    1106 Words  | 5 Pages

    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

  • Investigating the Effect of Concentration on the Rate of Diffusion

    643 Words  | 3 Pages

    Investigating the Effect of Concentration on the Rate of Diffusion Aim: To find out if concentration affects the rate of diffusion. Prediction: I predict that the higher the concentration of acid the faster the reaction will be. Hypothesis: Diffusion is the spreading out of a gas or liquid from an area of low concentration to another area where it has a lower concentration until the overall concentrations are balanced. The Hydrochloric acid (HCl) diffuses into the gelatine cube of which

  • Investigating the Movement of Osmosis through a Selectively Permeable Membrane

    results of potato tissue's mass difference, when placed in different concentrations of sugar solutions. This investigation would expect to have 3 different variables, Independent, which you can change, the thing that I will be changing in this investigation for the factors affecting osmosis, is the concentrations of the solution that changes the mass and investigate osmosis with potato tissues. The different sugar concentrations will be changed to see the result of the potatoes when placed in

    Investigating Osmosis Aim --- What is the effect of changing the concentration of Sodium Chloride Solution on potato cells? Prediction ---------- I predict that the lower the concentration of Sodium Chloride solution, the higher the final mass and length will be and the higher the concentration of Sodium Chloride solution, the lower the final mass and length. [IMAGE][IMAGE]I also think that with a concentration of 0 and 1 molar, the change in mass and length will be greater

  • Marble Chips Experiment

    601 Words  | 3 Pages

    Marble Chips Experiment Pilot Aim: To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. Prediction: I predict that the more hydrochloric acid there is the faster the chemical reaction. I also predict that the more dilute the acid is (the more water there is with the acid) the slower the chemical reaction. Hypothesis: I predicted what I did because the more concentrated the hydrochloric acid is the more energy there will be and
