EFFECTS OF OSMOSIS Osmosis is the diffusion of water across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. ISOTONIC SOLUTION HYPERTONIC SOLUTION isotonic isotonic A solution is isotonic to a cell if it has the same concentration of solutes as the cell. Equal amounts of water enter and exit the cell, so its size stays constant. hypertonic hypotonic A hypertonic solution has more solute than a cell. Overall, more water exits a cell that is in a hyper- tonic solution, causing the cell to shrivel or even die. HYPOTONIC SOLUTION hypotonic hypertonic A hypotonic solution has less solute than a cell. Overall, more water enters a cell that is in a hypotonic solution, causing the cell to expand or even burst.

A solution of water and dissolved ions is separated by a selectively permeable membrane that allows the passage of water but not small ions. The concentration of sodium is higher on one side of the membrane than onthe other side. However, there is no net movement of water across the membrane. How is this possible?
Given a selectively permeable membrane that is permeableto water but not to a particular solute and given that thereare different solute concentrations on the two sides of themembrane, show the direction of water movement and labelthe side with the higher osmotic pressure.
If two solutions with different osmolarities are separated by awater-permeable membrane, why will a change occur in thevolumes of the two compartment?

In osmosis, water flows from hypertonic/hypotonic/isotonic solutions to hypertonic/hypotonic/isotonic solutions, until both solutions are hypertonic/hypotonic/isotonic.
1) a) Draw arrows to indicate which direction Na+ vs K+ions will tend to move.(into vsout of the cell) b) What prevents these solutes from diffusing across the membrane at a significant rate? c)If the solutes were unable to move across the membrane, would the cell be considered hypertonic, hypotonic or isotonic? d) If the solutes were unable to move across the membrane, which way would water move?(inside the cell, outside the cell or no net movement) e) How did the cell establish the differential in the shown ion concentrations in the first place?

When a person becomes dehydrated the amount of water in extracellular fluids such as blood decreases, causing the solute concentration of these fluids to increase. State weather osmosis results in water entering or leaving cells.
A phospholipid bilayer separates two chambers. The chambers both contain the same volume of water. The left chamber contains 150 mM of an unknown solute A. Solute B is dissolved in the right chamber also at a concentration of 150 mM. Therefore, the initial osmolarity is the same (isotonic) between the two chambers. However, after a short time, the volume increases substantially in the right chamber. What is the most likely ranking of permeability for the molecules to cause this change? (greater permeability means that the molecule moves first across the membrane)
