2. When a cell is placed in a solution, water will move out of the cell, causing it to shrink.
3. transport moves substances against their concentration gradient.
1. Briefly explain the difference between passive transport and active transport.
2. Describe the structure of the cell membrane and explain how it contributes to its function as a selective barrier.
