• 2. passive transport

• 2. osmosis.

• 2. permeable

There is a higher solute concentration outside the cell.

To balance this, water will move out of the cell, causing it to shrink.

• Hypertonic Solution

• Hypotonic Solution

• Isotonic Solution

NGSS.MS-LS1-5

There is a higher solute concentration inside the cell.

Water will rush into the cell, causing it to swell and possibly burst.

• Hypertonic Solution

• Hypotonic Solution

• Isotonic Solution

NGSS.MS-LS1-3

There are equal concentrations of solute inside and outside the cell, and the net movement of water is zero.

• Hypertonic Solution

• Hypotonic Solution

• Isotonic Solution
