Hypertonic+Solution 

Hypertonic Solution

What is Hypertonic Solution? A hypertonic solution is a solution containing a high concentration of solutes. When a cell is put into a hypertonic solution will lose water, causing it to get smaller.Water moves out of the cell and the cell membrane pulls away from the cell membrane, plasmosis.

What do the Parts of the Term Mean? “Hyper” means over (as in hyperactive), while “tonos” means stretching.

When Were the Ideas for This Cell Transport Concept First Explored? The ideas were first explored in 1913.

Which Scientists Have Been Involved in the Development of the Concept? Loeb and Wasteneys found that hypertonic solutions were made by increasing the concentration. They experimented with adding hypertonic solutions to different cells and objects.

How Does it Affect an Animal Cell? When an animal cell is put into a hypertonic solution, it loses water and shrivels.

How Does it Affect a Plant Cell? When a plant cell is put into a hypertonic solution, the cell membrane pulls away from the cell wall but stays connected by points called plasmodesmata.

Is it Ever Dangerous to the Cell? It is dangerous to cells because it takes the water out of the cell and that causes it to get small and die.

Example in Human Body- In the brain, there are proteins call osmoreceptors, that are meant to regulate the amount of water in the body. When the body becomes a hypertonic solution, it is because there’s not enough water in the blood for the solutes. Water is added back to the bloodstream by the kidney reabsorbing it. After this process, the blood becomes more isotonic than the cells.

This is an analogy because salt molecules when added to water, dehydrate the water. When a cell is put into a hypertonic solution, it takes the water out of the cell.
