Compare the functions of the cell wall and the cell membrane in a plant cell.

• Both provide energy for the cell.

• The cell wall provides structure and support, while the cell membrane controls what enters and leaves the cell.

• Both store nutrients for the cell.

• The cell wall controls cell division, and the cell membrane makes food.

A student observes a green structure in a plant cell under a microscope. Which process is most likely happening in this structure, and why is it important?

• Respiration; it releases energy from food.

• Photosynthesis; it produces food for the plant.

• Digestion; it breaks down waste.

• Reproduction; it creates new cells.

Explain why plant cells need both mitochondria and chloroplasts.

• Mitochondria make food, and chloroplasts store energy.

• Chloroplasts make food through photosynthesis, and mitochondria release energy from food.

• Both organelles control cell division.

• Both organelles provide structure to the cell.

A plant cell is placed in a solution with very little water. Predict what will happen to the vacuole and explain your reasoning.

• The vacuole will fill with water, making the cell swell.

• The vacuole will shrink, causing the cell to wilt because water leaves the vacuole.

• The vacuole will divide into two.

• The vacuole will turn into a chloroplast.

A scientist removes the cell wall from a plant cell. What effect would this most likely have on the cell, and why?

• The cell would become more rigid because it has no wall.

• The cell would lose its shape and be more likely to burst because the cell wall provides structure and protection.

• The cell would start making more food.

• The cell would stop storing water.
