Percent Change in Mass of Zucchini Cores at Different Molarities of Sucrose If a potato is allowed to dehydrate by sitting in the open air, would the water potential of the potato cells decrease or increase? The water potential of the potato would decrease because water moves from a high water potential region to a low potential region, and a dehydrated potato cell is hypertonic in comparison with the environment. The concentration of solute would increase and osmotic potential would decrease. If a plant cell has a lower water potential than its surrounding environment, and if pressure is equal to zero, is the cell hypertonic or hypotonic to its environment?

Practical Examples of Osmosis in Medicine Basically, this concept becomes important when we start to administer hypertonic or hypotonic solutions. This means that the red blood cells themselves will no longer be capable of carrying oxygen and serving their purpose.

Now, so long as the canula is in a large vein, it will be able to draw fluid from a large area. However, if the canula is inserted in a small vein or accidentally inserted into the intersitial space and not a vein, it will not be able to draw fluid from all over, and consequently draw all the fluid from the surrounding cells.

This will cause the cells to shrink crenate and again, become unable to sustain life. In these circumstance, patients may develop cellulitis or damaged veins.

Examples of Osmosis in Cells? This becomes important when looking at the structure of cells in biology. If a cell has a high concentration of a solute salt it will draw fluid into its cell.

If allowed to continue to do this, it will eventually swell up and rupture this is called cell lysis. If a cell has a low concentration of a solute it will lose fluid as the fluid within its cell is allowed to be drawn out of the cell through osmosis and into the intersitial space. This will cause the cell to shrink this is called cell crenation.

If you put rice into a bowl of water, the water will move into the rice causing them to swell, while causing the water level to drop. Example of osmosis 3. This will cause the cell to shrink crenate.

Example of osmosis 4. In medicine, if a patient drawns in salt water, the hypertonic water in the lungs will cause more fluid to be drawn out of the pulmonary arteries into the alvioli and lungs.

This will more often result in pulmonary oedema than a patient who has drawned in fresh water. Example of osmosis 5. Now, if you were to give mannitol which is a very hypertonic solution the fluid within the blood will be drawn out of the cells and into the mannitol solution.

Example of osmosis 6 When the stem of a plant is cut and placed in water for example a vasethe water will move up through the stem by a process of osmosis, in which the water is flowing to the higher concentration of solvents found in the plant.

By understanding these examples of osmosis you will be able to better apply the concept of osmosis to practical uses in medicine, paramedicine, nursing, and many fields of general science.
