• Biome
• Community
• Population
• Organism

In a forest ecosystem, which of the following organisms are responsible for breaking down fallen leaves and dead animals?

• Autotrophs

Which of the following statements is part of the cell theory?

• Cells are composed mostly of empty space.
• Cells are generally large enough for the unaided eye to see.
• All cells are produced from existing cells.
• Only animals are made up of cells.

Complete the statement: This cell is ______ because it ______________.

• eukaryotic, contains a nucleus
• prokaryotic, does not contain a nucleus
• from a plant, contains a nucleus
• from an animal, contains a nucleus

The cells of all organisms contain DNA. In cells of which of the following groups is the cellular DNA enclosed in a nucleus?

• bacteria
• eukaryotes
• prokaryotes
• viruses

5. Lysosomes are organelles that contain enzymes. Which of the following is a function of lysosomes?

• Lysosomes build lipids, carbohydrates, and proteins.
• Lysosomes package lipids, carbohydrates, and proteins.
• Lysosomes break down lipids, carbohydrates, and proteins.
• Lysosomes store lipids, carbohydrates, and proteins.

6. What is the primary function of cell membrane?

• To store nutrients
• To produce energy
• To make proteins
• To controls what enters and exits the cell.

7. In eukaryotic cells, a number of organelles allow the cell to produce and distribute proteins. Where are proteins modified, sorted, and packaged?

• tells which proteins to make when
• break down cell parts for recycling or waste

• makes proteins
• uses the energy in sugar to make a molecule the cell can use
• tells which proteins to make when
• break down cell parts for recycling or waste
