Read each question carefully and answer to the best of your ability. This worksheet covers passive transport mechanisms in cells.
1. Which of the following is NOT a type of passive transport?
Diffusion
Osmosis
Active Transport
Facilitated Diffusion
2. The movement of water across a selectively permeable membrane from a region of high water concentration to a region of low water concentration is called:
Diffusion
Osmosis
Active Transport
Endocytosis
1. Passive transport does not require to move substances across the cell membrane.
2. Molecules move from an area of high concentration to an area of low concentration during .
3. The cell membrane is permeable, meaning it allows some substances to pass through while blocking others.
1. Facilitated diffusion requires energy from the cell.
True
False
2. Osmosis is the diffusion of solutes across a membrane.
True
False
1. Describe the main difference between simple diffusion and facilitated diffusion. Refer to the image of the cell membrane below.
2. Explain why passive transport is important for cell survival.
Match each term on the left with its definition on the right.
1. Diffusion
a. Movement of water across a semipermeable membrane
2. Osmosis
b. Movement of molecules from high to low concentration
3. Facilitated Diffusion
c. Movement of molecules with the help of transport proteins
