Introduction
To understand how osmosis and diffusion worked we did a lab. The lab we did was on plant cells and animal cells. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, equalizing the concentrations on each side of the membrane. Diffusion is the passive movement of molecules or particles along a concentration gradient or from regions of higher to regions of lower concentration. The difference between diffusion and osmosis is that diffusion refers to the movement of any chemical from one place to another, and osmosis exclusively refers to the movement of water across a membrane. Also, the lab that we did helped us to understand the difference between the three types of solutions. The three types of solutions are hypertonic, isotonic and hypertonic. An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. A hypotonic solution has a lower osmotic pressure than any other solution. A hypertonic solution is when the concentration of the solutes is greater outside the cell than inside of the cell. Tonicity is the measure of the effective osmotic pressure gradient, as understood by the water potential of two solutions separated by a semipermeable membrane. We
