Pictured is a cell in a hypotonic solution. Which direction did the water move across the membrane?

• It did not move

• Out of the cell

• Into the cell

Match the following

• Low water concentration outside the cell

• Hypertonic

• High water concentration outside the cell

• Hypotonic

• Equal concentrations of water on both sides of the membrane

• Isotonic

Match the following

• Hypertonic

• Water will move out of the cell

• Isotonic

• Water will move into the cell

• Hypotonic

• Water will remain the same on both sides of the membrane

In a ​hypotonic solution, there is a ​ (a)   solute concentration and a ​ (b)   water concentration inside the cell.

• high
• low
• equal

What will most likely occur when a cell is placed in a saline solution with a higher salt concentration that the interior of the cell?

• Water molecules will move until the water concentration is the same inside and outside the cell

• Salt molecules will move until the salt concentration is the same inside and outside the cell

• Salt molecules will move out of the cell

• Water molecules will into the cell
