Osmosis is a process that occurs at a cellular level that entails the spontaneous net
movement of water through a semi-permeable membrane from a region of low solute concentration
to an area of high solute concentration in order to equalize the level of water in each region.
Involved in this process are hypotonic, hypertonic and isotonic solutions. A hypotonic solution is one
with a lower osmotic pressure, indicating that the net movement of water moves into the said
solution whereas a hypertonic solution is one with a higher osmotic pressure, thus the net
movement of water will be leaving the hypertonic solution. Lastly, an isotonic solution entails no net
movement of water across a semi-permeable membrane as the two substances involved display
