An example of this process is the diffusion of a smell in a room. Eventually dynamic equilibrium will be reached. This means that the concentration of the molecules carrying the smell will be approximately equal through out the surrounding enclosed...
Hypotonic solutions are the opposite of hypertonic solutions. A solute is what is being dissolved by the solvent water is the most common solvent in a solution. Water will always move from an area of higher water potential to an area of lower water...
If water moves into the cell, the cell may lyse, or burst in animal cells, plant cells are equipped to handle large intakes of water. Water movement is directly proportional to the pressure on a system. Pressure potential is usually positive in living cells and negative in dead ones. Diffusion and osmosis are not the only processes responsible for the movement of ions or molecules in an out of cells. Active transport is process that uses energy from ATP to move substances through the cell membrane. Normally, active transport moves a substance against its concentration gradient, that is to say from a region of low concentration to an area of higher concentration.
Hypothesis: Osmosis and diffusion will continue until dynamic equilibrium is reached and net movement will no longer occur. Diffusion is effected by the solute size and concen-tration gradient across a selectively permeable membrane. Water potential greatly determines the results in sections of the experiment. Exercise 1A For this exercise, the following materials are required: a 30 cm of 2.
Exercise 1B This exercise of the experiment requires six strips of 30 cm dialysis tubing, ml beaker, 12 dialysis tubing clamps, funnel, six cups, distilled water, an electronic balance, timer, paper towels, and about 25 ml of each of these solutions: distilled water, 0. For recording results, paper and pencil are necessary. Exercise 1C This part of the experiment requires a large potato, potato corer about 3 cm long , ml beaker, paper towels, scale, six cups, knife, paper, pencil and about ml of each of these solutions: distilled water, 0. Exercise 1D This section requires a calculator, paper, pencil, and graphing paper. Exercise 1A First, soak the dialysis tubing in distilled water for 24 hours. Before handling the tubing, wash dirty hands thoroughly to prevent getting oils on the dialysis tubing and changing the results. Remove the tubing and tie off one end using the clamp. To use the clamp, twist the end of the bag several times and then fold it onto itself.
Next, open the other end of the tubing by rubbing the end between two fingers. Use the glucose tape by dipping it into the solution. Record the color change of the tape and the color of the bag. Tie of the end with the tubing clamp. It is necessary to leave space for expansion but no air. Record the color change. Use glucose tap to test for any glucose in the water. Record these results. Set the dialysis tubing in the beaker and let it sit for about 30 minutes. Remove the bag and record the change in water and bag color. Use the last two pieces of glucose tape to measure the glucose in the water and bag. Record results. Exercise 1B First, soak the dialysis tubing for about 24 hours. Again be sure to cleanse hands. Tie off one end of each tube with the clamps.
Next, fill each tube with a different solution distilled water, 0. Weigh each bag separately on the electronic balance and record the masses. Soak the bags in separate cups filled with distilled water for about 30 minutes. Remove the bags and gently blot dry with paper towel. Reweigh, and record the mass. Exercise 1C First, slice the potato into to 3-cm discs. Use the potato corer to core out 24 cores. Weigh 4 cores together and record their mass. Fill each cup with one of the following solutions: distilled water, 0. In each cup put 4 potato cores, and allow them to sit over night. Take out the cores and blot them dry. Again weigh them on the electronic scale. Record the change in mass. Calculate the information for the table. Compare the results with another group. Exercise 1D First, determine the solute potential of the glucose solution, the pressure potential, and the water potential. Graph the information given about the zucchini cores. Exercise 1E Prepare a wet mount slide of dyed onion skin.
Observe under a light microscope and sketch how the cells appear. Add a few drops of the salt solution using a paper towel to wick the solution under the slip. Observe how the cells are effected and make another sketch.
