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

Although “A Raisin in the Sun” mainly focuses on the dreams of the main characters‚ Lorrain Hansberry reveals the significance of the minor character‚ which motivates in political focus of many African Americans and develops the thematic messages in the play. Kristin Matthews asserts that “A Raisin in the Sun” reflects the conflicts of the African Americans have had in the mid-century. Matthews reproduces the studies of scholars to examine the racial struggles of home ownership and compares black

Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue

THE AFFECTS OF DIFFERENT SUCROSE SOLUTIONS ON OSMOSIS OF EGG MEMBRANES A laboratory report submitted for LE@D Biology 1004 Michele Liveley Arkansas State University Mountain Home Mountain Home‚ AR September 2013 Osmosis Egg Lab Report Introduction Osmosis is the passing of water or other solutions from an area of high concentration of particles to an area of less concentration. The cell membrane is an organelle‚ selectively permeable‚ and only

Osmosis and the Egg Lab Report By: N. Mullins Date: January 20‚ 2011 Introduction This lab was designed to explain the different things osmosis does. Osmosis is the diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually

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
