Honors Biology: Cells & Transport

Which of the following is a function of the cell membrane?

• breaks down lipids, carbohydrates, and proteins from foods
• stores water, salt, proteins, and carbohydrates
• keeps the cell wall in place
• regulates the movement of materials into and out of the cell

The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?

• carbohydrates
• lipids
• bilipids
• proteins

The diffusion of water across a selectively permeable membrane is called

• osmotic pressure.
• osmosis.
• pinocytosis.
• active transport.

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes

• water to move into the cell.
• water to move out of the cell
• solutes to move into the cell.
• solutes to move out of the cell.

Which means of particle transport requires input of energy from the cell?

• diffusion
• osmosis
• facilitated diffusion
• active transport

Which means of particle transport is shown in this diagram?

• diffusion
• osmosis
• facilitated diffusion
• active transport

Which means of particle transport is shown in this diagram?

• endocytosis
• exocytosis
• facilitated diffusion
• protein pump

The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called

• perforated
• non-conductive
• semi-permeable
• permeable

In pure water, a red blood cell from an animal will swell and burst, but a leaf cell from a plant will not. Which structure in the leaf cell is responsible for this difference?

• cell membrane
• cell wall
• mitochondrion
• nucleus

What organelle controls and regulates cellular activity?

• Ribosome
• Nucleus
• Mitochondria
• Lysosome
