What happens to a cells when they are put in a higher concentration of water?
When a cell is placed in higher concentration of water then endosmosis of water in the cell takes place because in the cell water concentration is low and osmotic(solute) pressure is high so water moves from its higher concentration towards its lower concentration which means it moves inside the cell and the cell becomes turgid.
Is water found in the cell membrane?
The same way that air influences the shape of a balloon. When the cell is in the proper environment water enters the cell and it is the proper shape. When the solute concentration outside the cell is too high the water leaves the cell and it shrivels.
What happens when there is a higher concentration of water outside the cell than inside the cell?
Water moves into the cell by osmosis along the concentration gradient until the two gradients are equal. The result is that the volume inside the cell increases, causing the cell to swell.
What will likely result if the concentration of electrolytes inside a cell is higher than in the extracellular environment?
If the concentration of electrolytes inside a cell is higher than in the extracellular environment it is called hyperosmotic. The cells will loose water and shrivel.
Which solution is hypertonic to red blood cells?
Red blood cells do contain some salts and other ions inside the cell. This means that if it is placed in water (assuming that it is deionized and has no solvent in it) the cell will be hypotonic because the concentration inside the cell will be higher than it is outside the cell.
Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell. Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell.

Why cell?
If placed in a hypertonic solution, cells will shrink because the solute concentration outside the cell will be higher than inside the cell. This causes the movement of water out of the cell (in order to equalise the concentration).
What will happen to a potato put in salt water?
In the salt solution the concentration of water inside the cells of the potato is higher than that outside. Therefore water molecules move from inside the potato where there is higher concentration of water molecules to outside the potato where there is a lower concentration of water molecules through semipermeable membrane of the potato cells. This process is called osmosis.
Osmosis in cells?
it occurs when water moves across a membrane to a lower concentration from a higher concentration.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
What is cells solution in which the concentration of dissolved substance in the solution is the same as concentration of dissolved substance inside a cell?
isotonic
Why must cells use energy to move particles from region of lower concentration to a region of higher concentration?
