Cells immersed in hypertonic solutions lose water and shrink, or crenate.
Water moves out of the cells into the hypertonic solution, causing the cells to shrink and become dehydrated.
Cells that are placed in a hypertonic solution of pure water tend to ___
Typical plant cells have a tonicity that is hypotonic to their environment, meaning they have a higher solute concentration than the surrounding environment. In contrast, typical animal cells have a tonicity that is isotonic to their environment, meaning their internal and external solute concentrations are balanced.
A common example of a hypertonic solution is a 10% salt solution. This means that the concentration of salt in the solution is higher than the concentration of salt in the cells. When cells are placed in a hypertonic solution, water will move out of the cells, causing them to shrink or crenate.
When the elodea leaf is moved from a salt solution back to water, the cells will undergo osmosis. Water will enter the cells in an attempt to dilute the higher concentration of salt that the cells accumulated while in the salt solution. This could lead to an increase in turgor pressure within the cells.

When placed in an isotonic solution (i.e. a solution where the concentration of water molecules is roughly equal to the that within cells), there is equal diffusion of water into and out of the cells. Therefore, the cells find this environment suitable. In a hypotonic solution (i.e. a solution where the concentration of water molecules is much more than that within cells) water diffuses into cells as a result of which the cells swell. Excessive swelling causes the cells to burst, a phenomenon called cell lysis In a hypertonic solution (i.e. a solution where the concentration of water molecules is lesser than that within cells) water moved out from within cells to the surrounding medium. As a result of this, cells shrink.
If you drink ocean water when your dehydrated it makes you even more so. In a hypertonic solution water moves out of the cells because the the particles want to have equal concentration gradients. Since a hypertonic solution has a high concentration of solutes in it it makes sense for the water from a cell to move out so that the environment in the cell and environment outside both have the same concentration of solutes. Human cells shrivel in a hypertonic solution, this kills the cells and can therefore kills you if enough cells can't function. answer: the indivdual dies
Cells that are placed in a hypertonic solution of pure water tend to ___
the molecules will pass from the salt solution to the cells.
An isotonic solution. This means that the concentration of solutes in the solution is the same as the concentration of solutes inside the cells, resulting in no net movement of water across the cell membrane.
When cells are bathed in an aqueous environment, it means they are surrounded by water. This is important for cellular processes to occur, as many biological reactions and interactions take place in a watery environment. Cells use this aqueous environment to transport molecules and nutrients, maintain their shape, and carry out essential functions for life.
Distilled water is used as a substitute for a hypotonic solution because it lacks solutes and has a lower concentration of particles compared to the intracellular environment of cells. This difference in concentration creates a concentration gradient that causes water to move into cells by osmosis, making distilled water hypotonic and able to potentially cause cell lysis.
The water will flow out of the cell into the hypertonic solution and the red blood cell will crenate (crush).
Aqueous solution.
Water moves out of the cells into the hypertonic solution, causing the cells to shrink and become dehydrated.
