If a solution surrounding a cell is hypertonic relative to the inside of the cell, how will water move?a. It will move into the cell via osmosis.b. It will move out of the cell via osmosis.c. It will not move, because equilibrium exists.d. It will evaporate from the cell surface more rapidly.

Seawater is hypertonic to cytoplasm in vertebrate cells and in plant cells. If a red blood cell and a plant cell were placed in seawater, what would happen to the two types of cells?

The concentration of solutes in a red blood cell is about 2%, but red blood cells contain almost no sucrose or urea. Sucrose cannot pass through the membrane, but water and urea can. Osmosis would cause red blood cells to shrink the most when immersed in which of the following solutions?

Green olives may be preserved in brine, which is a 30% salt solution. How does this method of preservation prevent microorganisms from growing in the olives?

A cell is placed in a solution that is hypotonic to the cell. Which of the following best describes movement of water in this situation?a. Water will only flow into the cell.b. Water will only flow out of the cell.c. Water will flow into and out of the cell, but the overall net movement will be out of the cell.d. Water will flow into and out of the cell, but the overall net movement will be into the cell.

What two conditions must be present for osmosis to occur?Integral membrane proteins are anchored in lipid bilayers.

A plant cell placed in distilled water will ______________; an animal cell placed in distilled water will ______________.a. burst … burstb. become flaccid . . . shrivelc. become turgid . . . be normal in shaped. become turgid . . . burst

The sodium concentration in a cell is 10 times less than the concentration in the surrounding fluid. How can the cell move sodium out of the cell? (Explain your answer.)a. passive transportb. receptor-mediated endocytosisc. active transportd. facilitated diffusion

DRAW IT An artificial 'cell' consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the 'environment,' as shown in the accompanying diagram. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose.a. Draw solid arrows to indicate the net movement of solutes into and/or out of the cell.b. Is the solution outside the cell isotonic, hypotonic, or hypertonic?c. Draw a dashed arrow to show the net osmosis, if any.d. Will the artificial cell become more flaccid, more turgid, or stay the same?e. Eventually, will the two solutions have the same or different solute concentrations?
