Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change
Premium Osmosis Chemistry Concentration
Purpose: To see the effects of tonicity’s on potato cells. Background: Osmosis is the diffusion of water across a differentially permeable membrane due to concentration differences. Tonicity is the concentration of solutes. The potato cell has 3% of dissolved materials. Hypertonic is when the solution has more dissolved materials outside the cell than inside. The cell will lose water this way and shrink. The potatoes in the 5% salt solution will shrink. Hypotonic is when there is less solute dissolved

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose

The cell membrane regulates and controls what kind of molecules ______ move in & out of the cell. 2. When molecules spread from an area of high to low concentration‚ it is called _Diffusion_____. 3. As molecules diffuse‚ they create a _concentration gradient_____

present in a potato plant. Polymers are large molecules consisting of many repeating units‚ called monomers. Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a

Diffusion and Osmosis Lab Introduction • What molecules can pass through a semi-permeable membrane? In this lab study we tested carbohydrates such as starch and glucose‚ as well as solutions like Benedict’s and Lugol’s to see if they would cross the membrane of a cell but since we can’t actually see that happen we used dialysis tubing (acts as the cell membrane). • My prediction was that glucose and Benedict’s could pass the semi-permeable membrane but starch and Lugol’s wouldn’t be able to

are in an area‚ the more collisions there will be. These collisions cause molecules to push away from each other. So‚ over time‚ the molecules of a substance will continue to spread out. Eventually‚ they will be spread evenly throughout the area. Osmosis is the diffusion of water. (when “the substance” that is diffusing is water)

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no
