Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease
