Osmosis/Diffusion Lab Report. Abstract: The effect concentration levels have on the process of osmosis. Intro: Osmosis is the diffusion of water across a semi-permeable membrane. With that being said, diffusion is the random movement of molecules from areas of high concentration to areas of high concentration.

What do you think happens to a plant when it is placed in salt water? Why might this occur?Discuss the answers to question 1 with the class.Osmosis is the diffusion of water across a selectively permeable membrane (i.e., cell membrane). Because of osmosis, water will move where water is less concentrated from an area of low solute (high water content) to an area with high solute concentration (low water content) (Figure 6.2). Dialysis tubing is used to model selectively permeable membr...
Step 1: Use a graduated cylinder to measure 250 mL of room temperature water in a beaker. Set aside. Obtain 1 piece of long and narrow dialysis tubing. Seal 1 end of the tube by tying a secure knot or attaching a dialysis tubing clamp to the end of the tubing. Put 10 mL of starch suspension and 10 mL of glucose solution in the tube. Then tie or cla...
Step 1: Hypothesize/Predict: Predict what would happen to the rate of osmosis if the surface area-to-volume ratio was large (as it would be with small cells compared to larger ones). Record your prediction. Step 2: Student-led planning:Determine how the rate of osmosis of water using a dialysis bag with starch solution is affected if surface area-t...
Would a large protein have difficulty crossing the membrane of a dialysis tube? Why or why not?Why do smaller cells have more efficient diffusion compared to larger ones?In this lab, we will make dialysis tubing “cells” and explore the effect of size on a molecule’s ability to diffuse through a “cell membrane.” The following information might be useful in understanding and interpreting your results in this lab: Phenolphthalein . Atomic formula: C 20 H 14 O 4; Atomic mass: 318.32 g/mol; Color in acidic ...
Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. This movement, down the concentration gradient, continues until molecules are evenly distributed. Osmosis is a special type of diffusion: the diffusion of water through a semipermeable membrane.
