    b.) The mass decreased or increased in each cylinder‚ depending on if the solution was hypotonic‚ hypertonic or isotonic. In Cylinder (A) the mass decreased‚ so liquid was released from the potato‚ because the cells in the potato would have burst if even more was absorbed‚ whereas the length stayed the same. In Cylinder (B) the mass and length increased‚ which means the potato cells absorbed some Sodium Chloride (NaCl)‚ so the cells don’t shrivel up and die. For Cylinder 3 the mass and length also

    that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to enter the inside of the cell. Osmosis is the process of water movement across the membranes from an area of high water concentration to an area of low water concentration to reach a sense of equilibrium. Diffusion is what enables osmosis to occur.

    Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked

    Practical Work Nº2: “Different methods to control osmosis” Aim: observe and test the process of osmosis through different kinds of methods: the weigh (potato)‚ the density (beetroot) and under the light microscope (onion). Hypothesis: according to the encyclopedia definition osmosis is the diffusion of a liquid (most often assumed to be water‚ but it can be any liquid solvent) through a partially-permeable membrane from a region of high solvent potential to a region of low solvent potential. Thus

    Introduction This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the

    Sophie Murdock Osmosis Lab Osmosis in Plant Cells: Solution Initial Volume (mL) Final Volume (mL) Percent Change Distilled Water 0.8 1.0 125% 0.4% NaCl 0.5 0.8 160% 0.9% NaCl 0.6 0.8 133% 5% NaCl 0.6 0.5 83% 10% NaCl 0.6 0.5 83% 8. The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions

    Biology Lab #1: Chemical Diffusion Purpose To discover how the size of a cell affects the diffusion of chemicals throughout the cell. Hypothesis I predict that as the cell size increases the diffusion depth and the diffusion rate will decrease.

    AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

    Title: Egg Osmosis Purpose: The purpose for doing this lab is to show how Osmosis takes place. It is supposed to show how the eggs would react to a change in their environment. The way to show how it would change would be putting eggs in different controlled environments. Each of the eggs will be put in three different environments. Vinegar‚ Karo Syrup‚ and water. Each egg will have to have a documented reaction that each will have. Introduction: The lab will allow us to see and explain each
