Read each question carefully and answer to the best of your ability. This worksheet will test your knowledge of cell transport mechanisms.
1. Which of the following processes does NOT require energy for molecules to move across the cell membrane?
Active Transport
Endocytosis
Diffusion
Exocytosis
2. The movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration is called:
Diffusion
Osmosis
Facilitated Diffusion
Active Transport
1. Active transport moves molecules from an area of low concentration to an area of high concentration.
True
False
2. The cell membrane is impermeable, meaning nothing can pass through it.
True
False
1. The main component of the cell membrane is the bilayer.
2. is the movement of solute particles from an area of higher concentration to an area of lower concentration.
1. Briefly explain the difference between passive transport and active transport.
Observe the diagram of the cell membrane below and answer the question.
2. Based on the diagram, describe the primary function of the structures labeled as 'protein channels' in cell transport.
