Multiple Choice Questions (21 Questions)
1. The term "microbiology" refers to the study of...
• A) Only bacteria
• B) Organisms that are too small to be seen with the naked eye
• C) Only viruses
• D) All life forms, regardless of size
<details> <summary><strong> Correct Answer: B</strong></summary>
Rationale: Microbiology is the study of microorganisms (microbes) – living things that are too small
to be seen without magnification. This includes bacteria, archaea, fungi, protozoa, algae, and viruses
(though viruses are acellular). Option A (only bacteria) is too narrow. Option C (only viruses) is too
narrow. Option D includes macroscopic organisms (animals, plants), which are not the focus of
microbiology.
</details>
2. Which of the following is a TRUE statement about pathogens?
• A) All microorganisms are pathogens
• B) Only bacteria can be pathogens
• C) Pathogens are microbes that cause disease in susceptible hosts
• D) Pathogens are always beneficial to their host
<details> <summary><strong> Correct Answer: C</strong></summary>
Rationale: Pathogens are disease-causing microorganisms. However, the vast majority of microbes
are not pathogens (option A is false). Pathogens can be bacteria, viruses, fungi, protozoa, or prions
(option B is false). Pathogens cause harm, not benefit (option D is false). Option C is the correct
definition.

3. The scientist credited with first observing "animalcules" (bacteria and protozoa) under a simple
microscope is...
, • A) Robert Hooke
• B) Antoni van Leeuwenhoek
• C) Louis Pasteur
• D) Robert Koch
<details> <summary><strong> Correct Answer: B</strong></summary>
Rationale: Antoni van Leeuwenhoek (1632-1723) made simple microscopes (single lenses) and was
the first to observe and describe bacteria and protozoa, which he called "animalcules." Robert
Hooke (A) observed cells in cork (fungal hyphae) using a compound microscope. Louis Pasteur (C)
disproved spontaneous generation. Robert Koch (D) established the germ theory of disease.
</details>
4. The theory that living organisms can arise from non-living matter is called...
• A) Biogenesis
• B) Spontaneous generation (abiogenesis)
• C) Germ theory
• D) Cell theory
<details> <summary><strong> Correct Answer: B</strong></summary>
Rationale: Spontaneous generation (also called abiogenesis) is the outdated belief that life arises
spontaneously from non-living matter (e.g., maggots from meat, mice from dirty hay). Biogenesis
(A) is the opposite – life arises only from pre-existing life. Germ theory (C) states that microbes cause
disease. Cell theory (D) states that all living things are composed of cells.
</details>
5. Louis Pasteur's swan-neck flask experiment definitively disproved...
• A) The germ theory of disease
• B) Spontaneous generation
• C) The importance of handwashing
• D) The existence of viruses
<details> <summary><strong> Correct Answer: B</strong></summary>
Rationale: Pasteur's swan-neck flask experiment demonstrated that broth remained sterile
indefinitely because airborne microbes were trapped in the curve of the neck. When the flask was
tilted to allow the trapped dust to contact the broth, microbial growth occurred. This provided strong
evidence against spontaneous generation and supported biogenesis (life from life). Option A is
incorrect (Pasteur supported germ theory). Option C relates to Semmelweis and Lister. Option D is
not relevant.
