For a cell placed in a hypotonic solution, solutes will diffuse out of the cell with their concentration gradients. For a cell placed in an isotonic solution, their will be no net flow of water either into or out of the cell. Question 2 1 / 1 point The main difference(s) between active and passive transport of molecules across membranes is/are: Active transport is used to move molecules with their concentration gradients.
