Aims
1. To observe and investigate the effects of osmosis across the cell membranes of a plant. 2. To investigate the ability of different molecules to diffuse across a selectively permeable membrane.
Introduction
All living cells are enclosed by an outer covering known as plasma or cell membranes. In addition, these plasma membranes serve as barriers between different compartments in the body to confine processes and materials to certain locations. Examples of these processes are diffusion and osmosis which are the main physiological processes that play important roles in the body. Diffusion can be defined as the process by which molecules move ...
