. DRAW IT An artificial “cell” consisting of an aqueous solutionenclosed in a selectively permeable membrane is immersed ina beaker containing a different solution, the “environment,”as shown in the accompanying diagram. The membrane ispermeable to water and to the simple sugars glucose and fructosebut impermeable to the disaccharide sucrose.(a) Draw solid arrows to indicate the net movement of solutesinto and/or out of the cell.(b) Is the solution outside the cell isotonic, hypotonic, orhypertonic?(c) Draw a dashed arrow to show the net osmosis, if any. (d) Will the artificial cell becomemore flaccid,more turgid,or stay the same?(e) Eventually, willthe two solutionshave the same ordifferent soluteconcentrations?
. 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
