1. The process of protein synthesis occurs in which cellular structure?
A. Nucleus
B. Ribosomes
C. Golgi apparatus
D. Mitochondria
Answer: B) Ribosomes
Rationale: Ribosomes are the sites of protein synthesis, translating
messenger RNA (mRNA) into amino acid sequences to form proteins.
2. Which structure in the cell is responsible for packaging and shipping
proteins?
A. Nucleus
B. Mitochondria
C. Golgi apparatus
D. Lysosomes
Answer: C) Golgi apparatus
Rationale: The Golgi apparatus modifies, sorts, and packages proteins
for secretion or transport to other parts of the cell.
3. What is the term for an organism that can make its own food using
sunlight?
,A. Heterotroph
B. Autotroph
C. Decomposer
D. Herbivore
Answer: B) Autotroph
Rationale: Autotrophs, such as plants and some bacteria, can make their
own food through processes like photosynthesis or chemosynthesis.
4. In which phase of the cell cycle does DNA replication occur?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Answer: B) S phase
Rationale: DNA replication occurs during the S (Synthesis) phase of the
cell cycle to ensure that each daughter cell receives an identical copy of
the genome.
5. Which of the following is NOT a characteristic of meiosis?
A. It results in four genetically diverse haploid cells.
B. It occurs in somatic cells.
C. It involves two rounds of division.
, D. It includes crossing over.
Answer: B) It occurs in somatic cells
Rationale: Meiosis occurs in germ cells to produce gametes (sperm and
egg), not in somatic cells. Somatic cells undergo mitosis.
6. What is the function of the Golgi apparatus in a cell?
A. Protein synthesis
B. Protein modification and packaging
C. DNA replication
D. Energy production
Answer: B) Protein modification and packaging
Rationale: The Golgi apparatus modifies, sorts, and packages proteins
and lipids for transport to their destination inside or outside the cell.
7. What process allows cells to take in liquids from the extracellular
fluid?
A. Phagocytosis
B. Pinocytosis
C. Receptor-mediated endocytosis
D. Exocytosis
Answer: B) Pinocytosis
Rationale: Pinocytosis is a type of endocytosis where the cell engulfs
extracellular fluid and dissolved solutes into vesicles.
A. Nucleus
B. Ribosomes
C. Golgi apparatus
D. Mitochondria
Answer: B) Ribosomes
Rationale: Ribosomes are the sites of protein synthesis, translating
messenger RNA (mRNA) into amino acid sequences to form proteins.
