What condition do animal cells prefer (hypotonic/isotonic/hypertonic)?
Suppose you have a cell from a freshwater fish that is isotonic with its surrounding environment, with a K+ concentration inside the cell of 0.05M. You then immerse this cell in saltwater where the K+ concentration is 0.25M. What would you predict will happen to the cell?
a)Water will move into the cell, and the cell will swell and burst
b)Water will move out of the cell, and the cell will shrink
c)Water will move in and out of the cell with no net change in concentration, and the cell will remain the same size
d)The cell wall will prevent the cell from changing size
If a scientist drops an animal cell into a solution that contains 10 times more salt than is found inside the cell, which of the following will happen? Hint: drawing a picture may help you.
A) The cell will burst since the solution is hypertonic
B) The cell will shrink since the solution is hypotonic.
C) The cell will burst since the solution is hypotonic.
D) The cell will shrink since the solution is hypertonic.
E) The cell will not change in size since the solution is isotonic.
