1. Which organelle is responsible for modifying and packaging
proteins?
A. Ribosome
B. Golgi apparatus
C. Lysosome
D. Nucleus
Correct Answer: B
Rationale: The Golgi apparatus processes proteins and prepares
them for secretion.
2. Which structure controls what enters and exits the cell?
A. Nucleus
B. Ribosome
C. Cell membrane
D. Cytoplasm
Correct Answer: C
Rationale: The cell membrane is selectively permeable.
3. Which macromolecule forms the primary structure of cell
membranes?
A. Protein
B. Carbohydrate
C. Lipid
D. Nucleic acid
Correct Answer: C
Rationale: Phospholipids form the bilayer of the cell membrane.
,4. Which organelle is the site of ATP production?
A. Lysosome
B. Mitochondria
C. Ribosome
D. Golgi
Correct Answer: B
Rationale: Mitochondria convert glucose into ATP via cellular
respiration.
5. Which process moves water from an area of low solute
concentration to high solute concentration?
A. Diffusion
B. Osmosis
C. Active transport
D. Facilitated diffusion
Correct Answer: B
Rationale: Osmosis is the movement of water through a
semipermeable membrane.
