We then poured 100 mL of the assigned sucrose solution into the cup and covered them with plastic wrap. To calculate solute potential at equilibrium, we used the formula Ψs = -iCRT. For this equation, every time a weight was recorded, we had to subtract it from the weight of the bag prior to the one being measured. Next, add several drops of 5% salt solution to the edge of the coverslip to allow the salt to diffuse under the coverslip. Diffusion osmosis post lab KEY.docx - Diffusion and Osmosis Post-Lab Directions: Answer the following questions within your group. Please be sure that | Course Hero. Osmosis is a selective form of diffusion. Factors affecting Water potential and Solute potential. But if we create our very own model of a cell, using a shell-less chicken egg, we can see what happens when we manipulate the osmotic balance in the "cell"!

Change in Weight Potato Cylinders Surrounded by Different Salt Concentrations. Place bag A in empty beaker and will with just enough 50% sucrose to cover the bag. Movement of iodine in solution.

Of the dialysis bags contained tap water. In particular, students find it challenging to understand that cells, like multicellular organisms, live in the environment and must perform all the actions necessary to stay alive. The passing of molecules is either through active transport (passage of materials using energy) or passive transport (passage of materials using kinetic energy). Next, we dipped a glucose test strip into the solution and recorded the initial glucose test results of the solution in Table 1 using a + symbol to indicate a positive result for glucose and a – for a negative result for glucose. Fill in the upper part of the document with the name of your educational institution. Osmosis is hard to see without a microscope. The starch still remained in the bag after 30 minutes. Perform this lab, we prepared each of the five bags with their designated sucrose solution. Campbell, Reece, Urry, Cain, Wasserman, Minorsky, & Jackson (2008). It is a simple lab where students do very little except watch the process and record data and information. There are several types of such errors: - Systematic error (precision) expresses the difference between the received and the actual values. Answer key diffusion and osmosis lab answers 2020. The higher the amount of sucrose causes for more water to move into the dialysis bag. White vinegar (about 3 cups).

Answer Key Diffusion And Osmosis Lab Answers 2020

For activity A, the hypothesis stated that if we added glucose-starch solution to a dialysis tubing bag and submerged it in a cup of distilled water and IKI solution then glucose will leave the dialysis bag through the pore into the IKI and distilled water solution through diffusion. The illustrated information mustn't duplicate that already provided in the text. Water is isotonic and moves freely across the cell membrane and helps maintain its fluid mosaic model characteristic. Seal one end of tube by tying it tightly like before. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration due to random molecular motion. Thankfully, though, the semipermeable membrane of the egg is much stronger, so you don't have to worry about the egg exploding as well! After soaking a piece of dialysis tubing in water, a group member rolled the tubing between their thumb and index finger to open it. A scientific lab report is one of the types of student's independent work.

If a hypothesis was formulated in the introduction, it is necessary to indicate whether it has been confirmed or refuted. The particles move from a higher concentration region to a low concentration region in diffusion. Initial||Final||Initial||Final|. Osmosis works just the same way in your cells as it does in our egg "cell" model. Effects of Concentrated Solutes on Cellular Membranes & Water Potential.

The membrane is semipermeable, meaning only specific molecule may enter the cell. If a cell shrinks when placed in a solution, then the solution is hypertonic to the cell. What are potential sources of error in this experiment? The introduction should justify the relevance of the work. By definition, a hypertonic solution is one that causes a cell to shrink. If the slide were warmed up, would the rate of motion of the molecules speed up, slow down, or remain the same? The movement of water across the cell membrane depends on the concentration of solutes on both sides of the cell membrane.

Its peculiarity is a generalization, abstractness, and an abundance of special scientific terms. 10% NaClWhich of these solutions is hypotonic to plant cells - 0. In doing so, we made sure the entire bag was covered by the solution in the cup. Hypotonic Solutions: A hypotonic solution is a solution that has a high concentration of solute inside the cell than outside. Cellulose membrane has tiny pores in it. However, phenolpthaleine and sodium hydroxide was able to move freely inside and outside of the bag, indicated by the color change to pink in both inside and outside of the bag (table 1). In the case of the hypotonic solution, there were more solutes in the egg than in the pure water.

The outside solution and the potato cells are not perfectly isotonic so 0. Include all the data for all four bags as four separate curves on the same graph. Now prepare your 2 dialysis tubing "bags.
