    Introduction: In this experiment I aim to investigate the effect of the surface area to volume ratio on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent:

    exterior and regulate the movement of substances in and out of the cell. Diffusion is how substances more in and out of the cell. There are several types of diffusion‚ but for the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the

    Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

    experiment‚ one of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the cells will gain

    Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

    the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

    Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

    Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing

    (3-6 pm) OSMOSIS LAB REPORT INTRODUCTION Osmosis is a special type of diffusion where water molecules move down a concentration gradient across a cell membrane. The solute (dissolved substance) concentration affects the rate of osmosis causing it either to speed the process up or slow it down. Based on this‚ how does different concentrations of sucrose affect the rate of osmosis? If sucrose concentration increases in the selectivity-permeable baggies‚ then the rate of osmosis will increase
