Which of the following structures is found in plant cells but not in animal cells?

• Nucleus

• Cell wall

• Mitochondria

• Ribosomes

Explain how the structure of the cell membrane contributes to its function in transport.

• The cell membrane is rigid, allowing only small molecules to pass.

• The cell membrane is selectively permeable, allowing certain molecules to pass while blocking others.

• The cell membrane is impermeable, preventing all substances from entering or leaving the cell.

• The cell membrane is permeable to all substances, allowing free movement in and out of the cell.

Compare and contrast the processes of photosynthesis and cellular respiration.

• Both processes occur in the mitochondria and produce glucose.

• Photosynthesis occurs in chloroplasts and produces glucose, while cellular respiration occurs in mitochondria and breaks down glucose.

• Both processes occur in chloroplasts and produce oxygen.

• Photosynthesis and cellular respiration both occur in the nucleus and produce ATP.

How does the structure of a plant cell differ from that of an animal cell?

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

• Plant cells have mitochondria, while animal cells do not.

• Plant cells have a nucleus, while animal cells do not.

• Plant cells have ribosomes, while animal cells do not.

What is the primary function of the cell membrane?

• To produce energy for the cell

• To control the movement of substances in and out of the cell

• To store genetic information

• To synthesize proteins

Explain how osmosis differs from diffusion.

• Osmosis involves the movement of solutes, while diffusion involves the movement of water.

• Osmosis involves the movement of water across a selectively permeable membrane, while diffusion involves the movement of solutes.

• Osmosis and diffusion are the same processes.

• Osmosis requires energy, while diffusion does not.

Which of the following are products of photosynthesis?

• Carbon dioxide and Nitrogen

• Oxygen and Glucose

• Nitrogen and Carbon

• Carbon Dioxide and ATP

What is the main difference between passive and active transport across the cell membrane?

• Passive transport requires energy, while active transport does not.

• Active transport requires energy, while passive transport does not.

• Both passive and active transport require energy.

• Neither passive nor active transport require energy.

Which of the following is a characteristic of prokaryotic cells?

• They do not have a nucleus.

• They have chloroplasts.

• They have a nucleus.

• They are multicellular.
