Biology formal lab report on osmosis and diffusion

Create two shell-less eggs using the first experiment. There were four infants affected by this cluster. Diffusion stops when the concentrations between these two becomes equal or has reached equilibrium. Osmosis is defined as the movement of water molecules, down its concentration gradient, from an area of high water concentration low solute concentration to an area of lower water concentration high solute concentration through a selectively permeable membrane. Concentration, Diffusion, Egg 708 Words 3 Pages Lab Report on Osmosis and Diffusion Biology 1, Period 3 March 15, 2010 Lab Team: Jason Perez, Kicia Long, Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. Some possible real-world uses for this knowledge are knowing why an egg might be the mass and circumference that it is. The results that we wrote down definitely did support our hypothesis because we expected the egg to grow a little bit when going through the hypotonic solution and we did expect our egg to shrink when it went through the hypertonic solution.

In contrast, corn syrup was hypertonic compared to the interior of the egg so water moved out of the egg. Measure the amount of water that moves across the egg's membrane. This shows that the water from the Coca-Cola went inside the egg but not the Coca-Cola itself. Introduction Osmosis is an example of passive transport. Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. Each of these tiny cells is surrounded by a membrane like our skin.

Diffusion and Osmosis Experiment with a Shell

Experiment 2 - The Eggsperiment with Syrup solution The second experiment conducted was the egg placed in syrup solution which allowed the egg to become deflated. Water always flows to the area with the most dissolved solutes, so that in the end both solutions have an equal concentration of solutes. The acetic acid of the vinegar will have broken up the calcium carbonate crystals, thus dissolving the shell. When our egg went through the hypertonic solution our egg's circumference became 16 cm. Diffusion is where the solutes move from an area of high concentration to a low concentration. Osmosis is the movement of the solvent molecules from the region of higher concentration to the region of lower concentration through a semi permeable membrane.

Eggsperiments Result, Discussion, and Conclusion

osmosis egg experiment lab report

Diffusion is the movement of particles from areas of high concentration to low concentration. Both diffusion and osmosis are forms of movement that are part of passive transport dealing with cell membranes. It was predicted that the eggs left in corn syrup and vegetable oil will go through plasmolysis and lose mass. Osmosis occurs until it reaches equilibrium, or when the concentration on each side is the same. Hypothesis: If the egg is placed in water, through osmosis the shell-less raw egg will increase in both size and mass and possibly lyse.

The size is to be recorded and so should the appearance of the egg on the table. Hypothesis: My hypothesis for this experiment is that the Gummy bear will absorb more of the plain tap and sugar water and the salt water will shrink the gummy Procedure: Materials- 3 clear cups, one spoon, 3 gummy bears, timer, tap water, salt, sugar. To conclude, the purpose of this lab was to observe the effect of diffusion, osmosis, and plasmolysis on eggs. Place 300 ml of water, corn syrup, red food coloring, cola, alcohol and corn oil in individual beakers mass each egg and record before placing one in each beaker let the egg soak in the solution for 48 hours remove the egg from the solution, mass and record observations Results: Mass of Egg in Grams Before and After 48 hours in Different Solution Solution Mass in Grams Before Mass in Grams After 48 Hours in Solution Water 73. Diffusion is the movement of molecules that between the. Osmosis is the movement of water across selectively permeable membranes. As a result, there will be no movement of any solutions on either sides of the membrane.

. Purpose: In this experiment that we performed we will learn about osmosis using dialysis membrane, a selectively permeable cellulose sheet that permits the passage of water but obstructs passage of larger molecules. Materials The materials used in this exercise were three raw eggs in a shell, measuring glass, an overflow bowl, a spoon, nine covers with lids, white vinegar, light corn syrup and a gallon of distilled water. One change that could be made to make the experiment more accurate and precise would be to record the mass of the clips and the dialysis bags at the same time. Using an electronic scale, the initial mass was measured and recorded of each egg. The prediction about the eggs soaked in water, cola, red food coloring, and corn syrup where correct. After this, the group will carefully place the raw egg into the jar and cover the egg with vinegar.

It could be concluded from our tests that the mass went down on the last day due to the egg being full of water, through osmosis it pumped water out through the membrane of the egg and thus, making the egg weigh less and look smaller. Their weights are checked again using the weighing machine. This may have caused the water that was coming or going out to not have access to the entire surface area of the membrane. The hypothesis cannot be considered completely correct unless there are no errors or disturbances throughout the experiment.

Methods Six unshelled eggs of predetermined weight were subsequently submerged in 0%, 10%, 20%, 30%, 40%, and x %. The above procedure is then repeated for the other eggs. Osmosis factors heavily in each of these processes and is an important force for keeping every single cell in your body healthy. As we learned that the potato slices with salt is bendable, we did an experiment with a different concentration of water. Osmosis is the movement of water across a selectively permeable membrane. The egg soaked in corn syrup went through the process of plasmolysis.

Introduction Cells have an outer covering called the cell membrane. The substances will move to the area of low concentration and this will make the egg hypotonic. For example the isotonic solution was only about 83. Materials: 10 eggs, 1 gallon vinegar, water, corn syrup, red food coloring, cola, alcohol, vegetable oil, a large container to soak the eggs in, six 400 ml beakers, digital balance Procedure: Soak the eggs in vinegar for 48 hours to remove the shell. Period: 4th 12-7-11 Statement of the Problem What will happen to the egg when a student tests osmosis with 3 different soultions in a cup. The reverse is also true as was the case for distilled water.
