SECTION 1: THE CELLULAR LEVEL (Questions 1–20)
1. Which organelle is known as the "powerhouse of the cell"?
o A. Nucleus
o B. Ribosome
o C. Mitochondrion
o D. Golgi apparatus
o Rationale: The mitochondrion produces ATP through cellular
respiration, supplying energy for cellular activities.
2. What is the primary function of ribosomes?
o A. Lipid synthesis
o B. Protein synthesis
o C. DNA replication
o D. Waste elimination
o Rationale: Ribosomes are the site of translation, where mRNA is
used to build polypeptide chains.
3. Which structure controls what enters and exits the cell?
o A. Cytoplasm
o B. Cell membrane
o C. Nucleolus
, o D. Centriole
o Rationale: The plasma membrane is selectively permeable and
regulates transport in and out of the cell.
4. Which phase of mitosis involves chromosomes aligning at the cell equator?
o A. Prophase
o B. Metaphase
o C. Anaphase
o D. Telophase
o Rationale: During metaphase, chromosomes line up along the
metaphase plate before separation.
5. What is the main function of the lysosome?
o A. Energy production
o B. Intracellular digestion
o C. Protein folding
o D. Hormone secretion
o Rationale: Lysosomes contain hydrolytic enzymes that break
down waste and cellular debris.
6. Which molecule carries genetic information from the nucleus to the
ribosome?
o A. tRNA
o B. rRNA
o C. mRNA
o D. DNA
, o Rationale: Messenger RNA (mRNA) transcribes genetic code and
carries it to ribosomes for translation.
7. Diffusion of water across a semipermeable membrane is called:
o A. Osmosis
o B. Active transport
o C. Phagocytosis
o D. Pinocytosis
o Rationale: Osmosis is the passive movement of water from low to
high solute concentration.
8. Which process requires ATP?
o A. Simple diffusion
o B. Facilitated diffusion
o C. Active transport
o D. Osmosis
o Rationale: Active transport moves substances against their
concentration gradient and requires energy.
9. What is the function of the nucleolus?
o A. Ribosome production
o B. Lipid storage
o C. ATP synthesis
o D. Protein degradation
o Rationale: The nucleolus synthesizes ribosomal RNA and
assembles ribosomal subunits.
10.Which of the following is NOT a phase of interphase?
, o A. G1
o B. S
o C. G2
o D. M
o Rationale: The M phase is mitosis, which occurs after interphase,
not within it.
11.Apoptosis is best described as:
o A. Cell division
o B. Programmed cell death
o C. Cell enlargement
o D. Uncontrolled growth
o Rationale: Apoptosis is a regulated, genetically programmed
process of cell self-destruction.
12.Which organelle detoxifies drugs and alcohol?
o A. Smooth endoplasmic reticulum
o B. Rough endoplasmic reticulum
o C. Peroxisome
o D. Nucleus
o Rationale: The smooth ER contains enzymes that detoxify drugs,
alcohol, and other harmful substances.
13.What is the role of the cytoskeleton?
o A. Energy storage
o B. Structural support and movement
o C. Genetic coding
