1. Which organelle is responsible for generating most of the
cell's ATP (energy currency) through cellular respiration?
A) Nucleus
B) Ribosome
C) Mitochondrion
D) Golgi apparatus
Answer: C
1
,Rationale: Mitochondria are often called the "powerhouses of the
cell" because they convert glucose and oxygen into ATP through
cellular respiration. They contain their own DNA and are thought
to have originated from endosymbiotic bacteria.
2. Which of the following structures is found in plant cells but
NOT in animal cells?
A) Cell membrane
B) Nucleus
C) Chloroplast
D) Mitochondrion
Answer: C
Rationale: Chloroplasts are the site of photosynthesis and contain
chlorophyll, giving plants their green color. They are found only
2
,in plant cells and some protists, not in animal cells. Both plant and
animal cells have cell membranes, nuclei, and mitochondria.
3. The primary function of the rough endoplasmic reticulum (RER)
is:
A) Lipid synthesis and detoxification
B) Protein synthesis and processing (due to attached
ribosomes)
C) Packaging and secretion of cellular products
D) Digestion of cellular waste
Answer: B
Rationale: The rough ER is studded with ribosomes, which
synthesize proteins that enter the ER lumen for folding and
processing. Smooth ER is involved in lipid synthesis and
3
, detoxification. The Golgi apparatus is responsible for
packaging, and lysosomes digest waste.
4. Which of the following statements about the cell membrane
(plasma membrane) is correct according to the fluid mosaic
model?
A) It is a rigid, static structure with identical lipids
B) It consists of a phospholipid bilayer with embedded
proteins that can move laterally
C) It is composed only of carbohydrates
D) It is impermeable to all substances
Answer: B
Rationale: The fluid mosaic model describes the cell membrane as
a dynamic structure with a phospholipid bilayer (hydrophilic
heads facing outward, hydrophobic tails inward) and various
