Cells & Microlife Test Review

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

• Only plants are composed of cells.

• All cells are produced from other cells.

• Cells can be produced from nonliving matter.

• Cells are one of several basic units of structure and function in living things.

Which of the following statements is correct?

• Prokaryotic cells lack a cell membrane

• Prokaryotic cells lack a membrane bound nucleus

• Prokaryotic cells do not carry genetic information

• Eukaryotic cells lack a nucleus

What is the function of a cell membrane?

• to support the cell

• to perform different functions in each cell

• to control what enters and leaves the cell

• to form a hard outer covering for the cell.

Which organelle is the control center of a cell?

• mitochondrion

• ribosome

• nucleus

• chloroplast

Which of the following best describes the function of the mitochondria?

• They convert energy from food molecules into energy the cell can use.

• They store energy from food molecules.

• They store energy from sunlight.

• They produce nucleic acids that release energy.

What is the function of a cell wall?

• to protect and support the cell.

• to perform different functions in each cell.

• to prevent water from passing through it.

• to prevent oxygen from entering the cell.

Which organelles store food and other materials needed by the cell?

• mitochondria

• chloroplasts

• ribosomes

• vacuoles

Which organelles release chemicals that break down large food particles into smaller ones?

• endoplasmic reticulum

• Golgi bodies

• lysosomes

• vacuoles

If you wanted to find DNA, where would you look?

• inside a cellʼs ribosome

• inside a cellʼs nucleus

• inside a cellʼs Golgi bodies

• inside a cellʼs vacuoles

What do lysosomes and Golgi bodies have in common?

• Theyʼre the twin “command centers” of the cell

• Theyʼre examples of cell organelles

• They break down food and release energy

• They control how much oxygen enters a cell
