Which of the following statements is true about osmosis?
Osmosis occurs when there is an imbalance of solutes outside of a cell versus inside the cell.
What happens to cells in a hypertonic solution?
Cells in a hypertonic solution will shrink as water leaves the cell.
What is the characteristic of a hypotonic solution?
A hypotonic solution has a lower concentration of solutes than another solution.
What is the role of an isotonic solution in maintaining homeostasis?
An isotonic solution maintains equilibrium by allowing an equal flow of water into and out of the cell.

Osmosis involves the movement of water molecules from an area of higher concentration to an area of lower concentration
What happens to cells in a hypertonic solution?
Cells in a hypertonic solution will shrink as water leaves the cell via osmosis

What is the characteristic of a hypertonic solution?
A hypertonic solution has a higher concentration of solutes than another solution
What is the process by which water molecules move across a semi-permeable membrane from an area of higher concentration to an area of lower concentration of water?
Osmosis
What happens to cells in a hypotonic solution?
They take on too much water and swell
