Biology Quiz on Cell Functions

Ciliated cells contain many mitochondria. What is the primary function of these mitochondria in a ciliated cell?

• To carry out photosynthesis.

• To store water and support the cell.

• To release energy for the movement of cilia.

• To control the cell's activities.

What is the main advantage of the long, thin extension on a root hair cell?

• It helps the plant anchor firmly in the soil.

• It increases the surface area for absorption.

• It stores food for the plant.

• It protects the root from damage.

Palisade mesophyll cells are packed with chloroplasts. What is the function of these chloroplasts?

• To release energy through respiration.

• To synthesize proteins.

• To control what enters and leaves the cell.

• To absorb light energy for photosynthesis.

Based on the comparison of a typical animal and plant cell, which of the following structures is found in a plant cell but not in an animal cell?

• Nucleus

• Cell membrane

• Cytoplasm

• Cell wall

What is the function of the large, permanent vacuole in a plant cell?

• It is the site of protein synthesis.

• It contains cell sap and helps support the cell.

• It releases energy for the cell.

• It contains the genetic material.

Which feature is characteristic of a bacterial cell but is absent in both plant and animal cells?

• Ribosomes

• A circular loop of DNA

• A cell membrane

• Cytoplasm

Both ciliated cells and root hair cells contain many mitochondria. This suggests that both cells carry out a high rate of which process?

• Photosynthesis

• Plasmolysis

• Aerobic respiration

• Cell division

Which organelle would be abundant in a palisade mesophyll cell but absent from a root hair cell?

• Mitochondrion

• Nucleus

• Chloroplast

• Ribosome

Which three structures are found in a ciliated cell, a root hair cell, and a palisade cell?

• Cell wall, chloroplast, nucleus

• Cell membrane, cytoplasm, nucleus

• Vacuole, cell wall, ribosomes

• Chloroplast, mitochondria, cell membrane

How is the genetic material organized in a bacterial cell compared to a plant cell?

• In a nucleus for bacteria, and in a plasmid for plants.

• In a circular loop of DNA for bacteria, and within a nucleus for plants.

• In ribosomes for bacteria, and in chloroplasts for plants.

• In a plasmid for bacteria, and in the vacuole for plants.
