100 Questions with Verified Answers and
Detailed Rationales
SECTION 1: Cell Theory & Cell Types (Questions 1-10)
Question 1: What are the three points of the Cell Theory?
A) Cells arise spontaneously, all cells are identical, cells are the
smallest unit of life
B) All organisms are composed of cells, cells are the basic unit
of life, cells arise from previous cells
C) Cells contain DNA, cells reproduce by mitosis, all cells have a
nucleus
D) Cells are invisible, cells live forever, cells have no function
☑ Correct Answer: B
Rationale: The Cell Theory has three fundamental tenets:
(1) all organisms are composed of cells, (2) cells are the basic
unit of life, and (3) cells arise only from pre-existing cells .

Question 2: Which of the following is a characteristic of
prokaryotes?
A) Membrane-bound organelles and a nucleus
B) Non-membrane bound organelles, no nucleus, smaller size,
and non-complex structure
C) Large size and complex internal structure
D) Presence of mitochondria and chloroplasts
☑ Correct Answer: B
Rationale: Prokaryotes (e.g., bacteria) lack membrane-
bound organelles and a nucleus. They are generally smaller and
less complex than eukaryotic cells .
Question 3: Which of the following is a characteristic of
eukaryotes?
A) No nucleus and no membrane-bound organelles
B) Smaller and less complex than prokaryotes
C) Membrane-bound organelles, nucleus, larger size, and
, 3
complex structure
D) Only found as single-celled organisms
☑ Correct Answer: C
Rationale: Eukaryotes (e.g., plants and animals) have
membrane-bound organelles, including a nucleus. They are
larger and more complex than prokaryotes .
Question 4: Bacteria are an example of which cell type?
A) Eukaryote
B) Prokaryote
C) Virus
D) Multicellular organism
☑ Correct Answer: B
Rationale: Bacteria are prokaryotic organisms—they lack a
nucleus and membrane-bound organelles .

Question 5: Plants and animals are examples of which cell
type?
A) Prokaryotes
B) Eukaryotes
C) Archaea
D) Viruses
☑ Correct Answer: B
Rationale: Plants and animals are eukaryotic organisms—
they have membrane-bound organelles including a nucleus .
Question 6: What are the four main types of tissue in the
human body?
A) Bone, blood, muscle, nerve
B) Epithelial, connective, muscular, nervous
C) Squamous, cuboidal, columnar, transitional
D) Cardiac, smooth, skeletal, nervous
