    Northern Kentucky University BIO 150L: Introduction to Biology I Instructor: Dr. Bethany Bowling Osmosis and Diffusion Report Estimating the Osmolarity of Plant Cells--Potato YAO ZHANG 03/26/2012 Introduction: It is undeniable that all cells have the kinetic energy. It will led the cells move randomly around to others. For this molecular movement‚ there are two results that might happen. Diffusion is one of them. Diffusion is the movement of molecules that between the

    process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

    OSMOSIS LAB BACKGROUND INFORMATION. Dialysis tubing is being used to model a plasma membrane. Isotonic solutions are solutions that have the same concentration of solutes on both sides of the membrane. Hypertonic solutions are solutions that have more solute to the one with less solute. Hypotonic solution are solutions that have less solute to the one with more solute. RESEARCH QUESTION:which dialysis tubing will gain the distilled water and which one will loss its content

    two main types of passive transport; diffusion and filtration (Marieb 68). In this experiment the focus is the importance of diffusion‚ the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse). Diffusion or osmosis occurs until dynamic equilibrium is reached‚ or has been reached. When equilibrium

    Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell

    Diffusion and osmosis are processes that are a constant in our lives‚ even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand‚ every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen and to

    solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0% salt concentration and 5% salt concentration but for 10%‚ 15%‚ 20% and 30% it went down in mass. This shows
