Question

A cell with 30% solute is in an environment that consists of 25% solute. Which statement is true?

A.water will move both into and out of the cell equally.
B. Water will move into the cell.
C. Water will move out of the cell.

Answer 1

Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.
