Section 1: Cell Biology and Organelles (Q1–Q25)
Q1: Which organelle is responsible for ATP production through oxidative
phosphorylation and contains its own circular DNA?
A. Endoplasmic reticulum
B. Golgi apparatus
C. Mitochondria [CORRECT]
D. Lysosome
,Correct Answer: C
Rationale: Mitochondria are the powerhouses of the cell, generating ATP via oxidative
phosphorylation. They contain mitochondrial DNA (mtDNA), which is circular and maternally
inherited. The ER synthesizes proteins and lipids; the Golgi modifies and packages
proteins; lysosomes contain hydrolytic enzymes for degradation.
Q2: Which structure is present in plant cells but absent in animal cells?
A. Plasma membrane
B. Cell wall [CORRECT]
C. Nucleus
D. Ribosome
Correct Answer: B
Rationale: Plant cells have a rigid cell wall made primarily of cellulose, which provides
structural support and protection. Animal cells lack a cell wall and instead have only a
plasma membrane.
Q3: Which organelle contains hydrolytic enzymes for intracellular digestion?
A. Peroxisome
B. Lysosome [CORRECT]
,C. Ribosome
D. Smooth ER
Correct Answer: B
Rationale: Lysosomes contain hydrolytic enzymes that break down waste materials, cellular
debris, and foreign pathogens through phagocytosis. They are also involved in autophagy
and programmed cell death (apoptosis).
Q4: What is the function of ribosomes?
A. Lipid synthesis
B. Protein synthesis [CORRECT]
C. DNA replication
D. ATP production
Correct Answer: B
Rationale: Ribosomes synthesize proteins by translating messenger RNA (mRNA) into
polypeptide chains. Free ribosomes synthesize cytosolic proteins, while bound ribosomes
synthesize proteins for secretion or membrane insertion.
Q5: The nucleolus is primarily responsible for:
A. ATP synthesis
B. Protein synthesis
, C. Ribosomal RNA synthesis and ribosome assembly [CORRECT]
D. Lipid metabolism
Correct Answer: C
Rationale: The nucleolus is a dense region within the nucleus that contains ribosomal RNA
(rRNA) genes and is responsible for assembling ribosomal subunits.
Q6: During which phase of mitosis do sister chromatids separate and move toward
opposite poles?
A. Prophase
B. Metaphase
C. Anaphase [CORRECT]
D. Telophase
Correct Answer: C
Rationale: Anaphase is characterized by the separation of sister chromatids at the
centromere, pulled by spindle fibers toward opposite poles. This is a checkpoint-controlled
event critical for genetic fidelity. Prophase involves chromatin condensation; metaphase
aligns chromosomes at the equatorial plate; telophase involves nuclear envelope
reformation.
Q7: A prokaryotic cell is characterized by:
