SECTION 1: MICROBIAL CLASSIFICATION & CELL STRUCTURE (Questions 1-30)
Q1. Which scientist performed an elegant series of experiments that finally and
definitively disproved the theory of spontaneous generation?
A) John Needham
B) Louis Pasteur
C) Francesco Redi
D) Lazzaro Spallanzani
Correct Answer: B. Louis Pasteur
,Louis Pasteur's famous experiments with swan-necked flasks demonstrated that
microorganisms do not arise spontaneously from nonliving matter. He showed
that sterilized broth remained sterile as long as it was protected from airborne
microorganisms, conclusively disproving the theory of spontaneous generation.
Q2. Which individual first observed unicellular organisms, which he called
"animalcules," using a microscope he developed?
A) Robert Hooke
B) Louis Pasteur
C) Antonie van Leeuwenhoek
D) Robert Koch
Correct Answer: C. Antonie van Leeuwenhoek
Antonie van Leeuwenhoek was the first to observe and describe single-celled
organisms, which he called "animalcules." He constructed his own simple
microscopes and is considered the father of microbiology for his pioneering
observations of bacteria, protozoa, and other microorganisms.
Q3. Which of the following was the first to use the term "cells"?
A) Antonie van Leeuwenhoek
B) Louis Pasteur
C) Robert Hooke
D) Robert Koch
,Correct Answer: C. Robert Hooke
Robert Hooke first used the term "cells" in 1665 to describe the microscopic
compartments he observed in cork tissue. His work in "Micrographia" laid the
foundation for cell theory.
Q4. What is the primary difference between prokaryotic and eukaryotic cells?
A) Prokaryotic cells have a nucleus; eukaryotic cells do not
B) Eukaryotic cells have a nucleus and membrane-bound organelles; prokaryotic
cells lack them
C) Prokaryotic cells are always multicellular
D) There is no significant difference
Correct Answer: B. Eukaryotic cells have a nucleus and membrane-bound
organelles; prokaryotic cells lack them
The primary distinction between prokaryotes and eukaryotes is the presence of a
true nucleus and membrane-bound organelles in eukaryotic cells. Prokaryotic cells,
such as bacteria and archaea, lack these structures and instead have a nucleoid
region where their DNA is located.
Q5. Which of the following is NOT a typical difference between eukaryotes and
prokaryotes?
A) Eukaryotic cells have membrane-bound organelles; prokaryotes do not
B) Eukaryotic cells typically have linear chromosomes; prokaryotes have circular
, chromosomes
C) Eukaryotic cells typically have circular chromosomes; prokaryotes have linear
chromosomes
D) Eukaryotic cells are generally larger than prokaryotic cells
Correct Answer: C. Eukaryotic cells typically have circular chromosomes;
prokaryotes have linear chromosomes
The statement that eukaryotic cells have circular chromosomes is false. Eukaryotic
cells typically have linear chromosomes, while prokaryotic cells typically have a
single circular chromosome. This is a key difference between the two cell types.
Q6. Which are the three currently accepted domains?
A) Bacteria, Fungi, and Eukarya
B) Bacteria, Archaea, and Eukarya
C) Prokaryota, Eukaryota, and Archaea
D) Monera, Protista, and Animalia
Correct Answer: B. Bacteria, Archaea, and Eukarya
The three-domain system, proposed by Carl Woese, classifies all life into Bacteria,
Archaea, and Eukarya. This classification is based on differences in ribosomal RNA
sequences, which reveal the evolutionary relationships between organisms.
Q7. Which of the following is NOT true of Archaeans?
