1. Which microscope objective provides the greatest
magnification?
A. 4×
B. 10×
C. 40×
D. 100× (oil immersion)
Rationale: The 100× oil immersion objective provides the
highest magnification and resolution on a standard
compound microscope.
2. The part of the microscope that regulates the amount of
light passing through the specimen is the:
A. Ocular lens
B. Stage
C. Iris diaphragm
D. Coarse adjustment knob
,Rationale: The iris diaphragm controls light intensity,
improving image contrast.
3. Which adjustment knob should be used for fine focusing
under high power?
A. Coarse adjustment
B. Stage clip
C. Condenser
D. Fine adjustment
Rationale: The fine adjustment knob allows precise focusing,
especially under high magnification.
4. Which organelle is responsible for ATP production?
A. Nucleus
B. Golgi apparatus
C. Lysosome
D. Mitochondrion
Rationale: Mitochondria produce ATP through cellular
respiration.
5. Which organelle modifies and packages proteins?
A. Ribosome
B. Golgi apparatus
C. Lysosome
D. Centriole
,Rationale: The Golgi apparatus processes, sorts, and
packages proteins for transport.
6. Which organelle contains digestive enzymes?
A. Rough ER
B. Smooth ER
C. Lysosome
D. Peroxisome
Rationale: Lysosomes contain hydrolytic enzymes that digest
cellular debris.
7. Which tissue has tightly packed cells with little
extracellular matrix?
A. Connective
B. Muscle
C. Nervous
D. Epithelial
Rationale: Epithelial tissue forms protective coverings and
linings with closely packed cells.
8. Simple squamous epithelium is specialized for:
A. Protection
B. Secretion
C. Diffusion
D. Contraction
, Rationale: Thin cells allow rapid diffusion and filtration.
9. Which tissue is found in tendons?
A. Areolar
B. Adipose
C. Dense regular connective tissue
D. Hyaline cartilage
Rationale: Dense regular connective tissue withstands tensile
forces in one direction.
10. Osteocytes are found in:
A. Cartilage
B. Blood
C. Muscle
D. Bone
Rationale: Osteocytes are mature bone cells located within
lacunae.
11. Which tissue has striations and multiple nuclei?
A. Cardiac muscle
B. Smooth muscle
C. Skeletal muscle
D. Nervous tissue
Rationale: Skeletal muscle fibers are multinucleated and
striated.
