A concentration gradient exists when there is

A difference between high and low concentrations

If a cell is placed in a solution with a HIGHER solute concentration than the cell,

The environment is called hypotonic

What did Virchow discover about cell reproduction?

That you can steal someone else's work and get credit

What is a selectively permeable membrane?

It lets some substances through but not others

In the following image, what will happen to the plant cell if it takes on water?

The membrane will expand but the wall will not
