After 20 minutes, remove the bags from the beaker, and carefully blot each one to remove excess water. This is considered a passive form of transportation because it does not require any additional energy to transport the molecules.
The equation to find the sum of water potential is: Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration.
Use the cork borer to cut out 24 potato cylinders. Weigh each one again on an electronic balance and record the masses on a table Table 1. Record data of percent change in mass onto the table Table 2. Each cylinder must be 3 cm in length. Once you have all 6 tubes filled with the solutions, remove excess air, and tie the tops with strings.
First pour mL of each of the solutions 0. Cover each beaker with plastic wrap. Water potential is affected by two factors: First, soak 6 dialysis tubing in distilled water until you can open one end. Group the 24 potatoes in groups of 4.
Osmotic potential is dependent on the solute concentration, and pressure potential which is the energy that forms from exertion of pressure either positive or negative on a solution.
The next day, record the temperatures of the sucrose solutions in each beaker. Next, get a mL beaker and fill it to mL with distilled water or tap water. The basic principles of Osmosis and Diffusion were tested and examined in this lab. Copy this data onto a table Table 2.
Look at the Results Section to see what the table layout should look like. Mark the tubes or string with markings so that you can distinguish between the varying concentrations of sucrose.
Record the temperature in the table Table 2. Record the initial masses of all the groups in the table Table 2. Next, fill each tube about half way with a different solution 0. Then place all 6 tubes in the beaker,and let them sit there for 20 minutes.In Part 1, what was the expected ratio of heads to tails for tosses of a single coin?
Did your results always agree with the expected ratio? If not, what would be a reason for the deviation? Documents Similar To Probability and Mendeilian Genetics Lab.

Lab 1: Diffusion and Osmosis Laboratory 1, AP Biology Spurthi Tarugu, Kavinmozhi Caldwell, Chelsea Mbakwe, Radha Dave, Navya Kondeti Abstract: The basic principles of Osmosis and Diffusion were tested and examined in this lab.
We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in.
