Passive and Active Transport

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.
• Into the cell, so the cell swells.

 If the volume of a cell increases when it is placed in a solution, that solution is said to be __________ to the cell

•  hypertonic
• subatomic
•  isotonic
•  hypotonic

Four students were asked to explain what this means. Which one is correct?

• Student 1: Cell membranes prevent all materials from entering the cell.

• Student 2: Cell membranes only provide structural support for the cell.

• Student 3: Cell membranes regulate which substances can enter and exit the cell.

• Student 4: Cell membranes allow water and water-soluble substances to enter the cell.
