    Lab Questions By Zackary Conte and Justin Dvorsak The first experiment with 1 M sucrose in the bag and distilled water in the beaker had almost exactly the same results. The masses were relatively the same the difference have could been from the amount of liquid that was placed inside of each of the bags. The second experiment with 5% Ovalbumin in the bag and 1 M sucrose in the beaker had almost exactly the same results. The masses were relatively the same the difference could have been from the

    lab will have water and substances diffusing though it in and out. The direction‚ in which things diffuse‚ depends on the type of solution the egg is placed in. A hypertonic solution isa solution that is outside the cell and it has lower free water molecule concentration than cytosol. Water diffuses out of the cell and the cell shrinks. A hypotonic solution is a solution that is outside the cell and it has a higher free water molecule concentration than cytosol. The water diffuses into the cell and

    known as Osmosis. Diffusion is the process by which molecules of a substance move from areas of higher concentration of that substance to areas of lower concentration. Diffusion can be the transfer of anything anywhere. However‚ that is not true for osmosis. Osmosis is diffusion‚ but a specific type of diffusion. Osmosis is only the diffusion of water molecules through a selectively permeable membrane and a concentration gradient. Only certain molecules can cross the membrane

    partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

    Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

    specialized type of diffusion called osmosis‚ “which involves in selective transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data

    the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the cell that outside which will cause water to diffuse out in attempt to reach equilibrium. Hypertonic solutions are when there is more water outside

    Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch
