Create a diagram that demonstrates the difference between tonicity and osmolarity. Be sure to label the new solutions in each condition, draw the changes (if predicted) in cell shape/volume, and use arrows to show the movement of water relative to the cell. Please start with a red blood cell in an isosmotic solution and show what happens to cell shape and water movement when NaCl is added to the solution, or when water is added.

Given the following cell type and solutions, draw the cell, showing the net direction of osmosis (water flow) and say what state the cell will be in. Choose from the following terms to describe the state of the cell: Turgid, flaccid, plasmolyzed, crenulated (shriveled), lysed (burst), normal. An animal cell with an internal osmolarity of 0.32 M (total concentration of all the solutes in solution) that is placed in a solution of 0.32 M NaCl.
Draw a beaker that is filled with water. Label the water with an osmolarity of 0.61M. In the water, draw a single Elodea cell (note: Elodea is an aquatic plant) with a cellular osmolarity of 0.42M. Name this drawing with the tonicity term that best describes the solution of the water in the beaker compared to the osmolarity of the Elodea cell. Then describe what will happen to the tonicity of the cell over time. Make sure to explain the direction that water will flow, small molecules will diffuse, and explain what will happen to this cell over time. Make sure you use all of the applicable tonicity terms in your description.
Name the solution in which the relative concentration of water molecules and the solute on either side of the cell is same.
Cells are placed in a beaker of water. The concentration of glucose outside of the cells is 3 mg/ml. The concentration of glucose inside of the cells is 33 mg/ml. Assuming glucose is the only solute, in which direction will osmosis occur? *
A cell with intracellular osmolarity of 280 mOsm/L is placed into three different containers varying in osmolarity. Which solution from the list would cause the cell to lose water and shrink? 280 mOsm/L 240 mOsm/L 340 mOsm/L NONE of the above
A cell containing 2% sucrose solution is placed in a hypertonic solution. A.) In one statement maximum, explain what a hypertonic solution is in reference to solute concentration. B.) In one statement, predict the direction of osmosis ( movement of water) C.) In one statement, predict the resulting change in the cell's shape.
In osmosis, water flows from hypertonic/hypotonic/isotonic solutions to hypertonic/hypotonic/isotonic solutions, until both solutions are hypertonic/hypotonic/isotonic.
Define the following terms:a. osmosisb. osmotic pressurec. isotonic solutiond. membrane potentiale. hydronium ion
The movement of water is called osmosis. Osmosis is the diffusion of water, and it too moves to reach equilibrium. The relationship between solute concentration and water are opposite. An area with high concentration of solute has less water "concentration", and an area of low solute concentration has a higher water "concentration". Select the options that describe the movement of water if there is a gradient across a membrane. Hint: There are two correct answers. One with the solute perspective and one with a water perspective. Select all that apply: Water moves from an area of high solute concentration to an area of low solute concentration. Water moves from an area of low solute concentration to an area of high solute concentration. Water moves from an area of high water "concentration" to an area of low water "concentration". Water moves from an area of low water "concentration" to an area of high water "concentration".
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)
Which statement best fits the following diagram? The purplish dots are sugar molecules and the blue areas are water molecules. On the left side the water molecwles have a concentration of 99.1% and on the right side the water molecules have concentration of 99.9%. 1) The level of fluid on the left will rise because water will move by osmosis through the membrane. 2) The level of the fluid on the left will fall as water moves to the right by osmosis. 3) The level of the water on the left will rise as a result of sugar molecules diffusing through the membrane. 4) The level of the water on the left will fall as sugar molecules diffuse through the membrane.
Information: Osmotic pressure is the pressure that a solvent exerts against a semipermeable membrane, such as a cell membrane. The higher the solute concentration, the lower the osmotic pressure. Red blood cells have an osmotic pressure equal to that of a 0.90% (m/v) solution of sodium chloride and 5.0% (m/v) solution of dextrose. A solution that has a higher concentration that this is called hypertonic; one with a lower concentration is called hypotonic. Osmotic pressure is an important factor affecting cells. Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.Hypertonicity is the presence of a solution that causes cells to shrink.Hypotonicity is the presence of a solution that causes cells to swell.Isotonicity is the presence of a solution that produces no change in cell volume.When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to…
