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?

Diagram of a cell in a beaker showing solute concentrations and membrane permeability for osmosis study.

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?

Accepted Answer

Hi everyone here we have a question telling us that a cell is placed in a B. Here containing a solution of simple sugars, glucose fructose and sucrose, which are the following direction of passive movements of substances is incorrect. Note that the plasma membrane is impermeable for dissect rides. So we have our cell here and out in the beaker, we have glucose, fruit toast and sucrose. So our substances are going to move from a high concentration to a low concentration passively. But we have glucose fructose and sucrose outside so they will be moving into the cell. So let's look at our answer choices. Water will move out of the cell. There's a lower concentration of water outside of the cell than inside of the cell. So this one is true B glucose will move into the cell. There is a higher concentration of glucose outside of the cell than inside of the cell. So it will move into the cell. So B. Is true. See fruit toast will move into the cell, There's a higher concentration of secrets outside of the cell than into the cell. So it will move into the cell. So C. Is true. D. Sucrose will move out of the cell. There is a higher concentration of sucrose outside of the cell than inside of the cell. So sucrose will not move out of the cell. It will move into the cell. So D. Is incorrect. So our answer here is the see chris will move out of the cell. Thank you for watching. Bye
