Blood Cell And Osmosis Experiment

In a cell, substance can move in and out without expanding energy; which is called passive transport. Think about molecules and ions move in motion in a solution. When a random motion cause a net movement of a substance of high concentration to low concentration is called diffusion. That is where the molecules spread out evenly throughout the area. When you have a difference in the concentration in a distance is called a concentration gradient. Random movement of molecules are called Thermal Molecular Motion. There are two factors that can effect the speed of a thermal molecules motion. The temperature of the solution and its molecular weight. The purpose of this experiment is to observe Brownian movement and it relationship to molecular movement. Find the direction and the rate of diffusion of their molecules of different sizes. Determine the direction and the rate of osmosis in and out of simulated cells in hypotonic, hypertonic and isotonic environments. Final purpose of this experiment is to find hypotonic, hypertonic and isotonic solution in a blood cell and hypertonic in a plant cell. To see how they affect the volume and the integrity of the …show more content…
Hemolysis is where the cell may destruct from the process of osmosis. The three solution provided in procedures 9.3 and you will also need three testing tubes. In the procedures it will be best to allow your instructor to drop the fresh sheep blood into the tubes. Four drops into each tubes. Cover the tubes with parafilm and then mix the contents. Once it is well mix, for each tube grab a paper and see if the writing material is visible then record your result. Grab an eyedropper to obtain one drop to the slide and then add a coverslip. Use a microscope to examine the blood cell. Use the low magnification first then the high. Determine if the cell condition as crenate, normal, or lysed. It is important to wash your hands after this lab especially working with blood
