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
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.
