Introduction: 1. The purpose of doing this lab was to recognize the effects that salt‚ in different strengths‚ has on cells. 2. Osmosis is the movement of water molecules
Premium Osmosis Water Diffusion
The lab was primarily based on osmosis and diffusion. Diffusion is when the movement of molecules from a high concentration that go to a low concentration to a high concentration to eventually reach an equilibrium. Osmosis is when water will diffuse from high water concentration to low water concentration to reach equilibrium. When the solutions are different the lower concentration solute is hypotonic while the higher concentration solute is hypertonic. The hypertonic solution would have a low water

carbon dioxide. Osmosis is a special type of diffusion‚ which occurs when water is diffused across the membrane. This can be affected by how hydrophilic a solute is on either side of the membrane. The diffusion of glucose‚ starch‚ and iodine was observed when the solutes went from a higher concentration of their individual solute to a lower concentration diffusing threw pores in the dialysis bag. The experiment sought to find out which solutes would diffuse threw the pores of the dialysis bag‚ whether

of molecules. The diffusion is a form of Brownian movement‚ or we can say The Brownian movement leads to diffusion in three different types‚ where the particles move from high concentration to low concentration area‚ which are hypotonic‚ hypertonic‚ and isotonic. 2- What was the role of the indicators (Lugol’s and Benedict’s solutions) used in the cell model experiment? Explain your answer using results you obtained from the cell model experiment. Lugol’s solution is a solution of elemental iodine and

Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

3. Describe the differences between animal and plant cells. Although plant and animal cells both have mitochondria‚ cytoplasm‚ and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells‚ as well as most eukaryotic cells. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles‚ but their functions are quite different. The purpose of vacuoles in

permeability‚ which is the ability of the membrane to pass a solution through it. Membrane permeability is crucial in the effectiveness of dialysis. Lastly‚ osmotic pressure is “the pressure that must be applied to stop the movement of solvent through the membrane” (p. 19 lab manual). Membrane permeability and osmotic pressure is demonstrated by using the dialysis tubing when submerged in distilled water‚ and the raw egg when immersed in the Karo syrup. Purpose: One goal of this experiment is to understand

What is the main difference between simple diffusion and facilitated diffusion? Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy.

point than pure water. The second property observed was osmosis pressure. This experiment used a 6 inch piece of dialysis tubing that was filled 2/3 full with light Karo syrup and tied off. Then it was completely submerged in a large glass bowl of room temperature distilled water. The dialysis tubing acts as a semi-permeable barrier and water passed through to inside the tube and over the next several hours‚ this act caused the tube to swell. Osmosis is where water moves from an area of high concentration
