Diffusion and osmosis
How will different concentration of sugar (independent variable) affect
Osmosis (dependent variable)
Diffusion is the movement of materials from areas of high concentration to the area of low concentration, whereas osmosis is the diffusion of water from area of high concentration to the area of low concentration through a semi-permeable membrane. The two processes are always important to the body since they are often involved in transport of substances and materials in the body like water and minerals. Osmosis and diffusion are related since they involve transport of materials from area of high concentration to the area of low concentration (concentration gradient). In osmosis concentration gradient of water is increased by adding more solutes in two different areas. The more solutes present in a solution, the less water present thus the low concentration of water in the solution. Conversely areas of high concentration of water will have low level of solutes and vice versa. The more solute present in a solution, the less room for water and thus the lower concentration of water. Nevertheless areas with less concentration of solutes will have high concentration of water. In the process of osmosis, the solutes are stopped from diffusing by the semi-permeable membrane thus only water is allowed to diffuse.
