Read each question carefully and answer to the best of your ability. This worksheet covers different ways substances move in and out of cells.
1. Which process involves the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration?
Diffusion
Osmosis
Active Transport
Facilitated Diffusion
2. The cell membrane is described as selectively permeable. What does this mean?
It allows all substances to pass through.
It blocks all substances from passing through.
It chooses which substances can pass through.
It only allows large molecules to pass through.
3. Which type of transport requires energy (ATP) to move substances across the cell membrane?
Passive Transport
Diffusion
Osmosis
Active Transport
1. The movement of molecules from an area of high concentration to an area of low concentration is called .
2. When a cell needs to move substances against their concentration gradient, it uses transport, which requires energy.
3. The controls what enters and leaves the cell.
1. Passive transport requires the cell to expend energy.
True
False
2. Osmosis is a special type of diffusion that involves the movement of solutes.
True
False
