CELL TRANSPORT REVIEW

1. CELL TRANSPORT REVIEW Read each of the following questions and record your answer on your whiteboard. When I coundown “3, 2, 1” hold up your whiteboard with the answer facing forward. Any team that has all correct answers will earn a point. The team with the most points at the end wins!

20. If a more-concentrated salt solution is on one side of a membrane and a less-concentrated solution is on the other side, water molecules tend to pass through the membrane • from the more-concentrated to the less-concentrated solution. • until the cell membrane is broken down. • from the less-concentrated to the more-concentrated solution. • equally in both directions.
