- Plants
- Animals
- Microorganisms
- Ecosystems
A: Microorganisms

Q: Which of the following is NOT a primary category of microorganisms?
- Bacteria
- Fungi
- Algae
- Mammals
A: Mammals

Q: How do bacteria differ from fungi in terms of cellular structure?
- Bacteria have a defined nucleus, while fungi do not.
- Bacteria are prokaryotic, while fungi are eukaryotic.
- Bacteria are multicellular, while fungi are unicellular.
- Bacteria have membrane-bound organelles, while fungi do not.
A: Bacteria are prokaryotic, while fungi are eukaryotic.

Q: Why is understanding microbial metabolism important in biotechnology?
- It helps in classifying microorganisms.
- It allows for the identification of pathogenic microbes.
- It aids in the development of microbial products like antibiotics.
- It enhances the growth of plants.
A: It aids in the development of microbial products like antibiotics.

Q: When do microorganisms typically reproduce rapidly?
- Under extreme conditions
- In the presence of pathogens
- Under optimal conditions
- When nutrients are scarce
A: Under optimal conditions

Q: Which of the following roles do microbes play in ecosystems?
- They are the only producers of oxygen.
- They are essential for nutrient cycling and decomposition.
- They are primarily responsible for animal reproduction.
- They have no significant ecological roles.
A: They are essential for nutrient cycling and decomposition.

Q: How does the human microbiome contribute to overall health?
- By causing diseases
- By promoting digestion and immunity
- By eliminating all pathogens
- By increasing the risk of infections
A: By promoting digestion and immunity

Q: What is the significance of the three-domain system in microbial classification?
- It simplifies the study of viruses.
- It categorizes life based on observable traits.
- It highlights genetic and evolutionary distinctions among organisms.
- It focuses solely on the ecological roles of microorganisms.
A: It highlights genetic and evolutionary distinctions among organisms.

Q: Which technique is commonly used in phenotypic classification of bacteria?
- DNA sequencing
- PCR
- Gram staining
- Bioinformatics
A: Gram staining

Q: Why is it important to integrate phenotypic, genotypic, and ecological data in microbial classification?
- To make classification easier
- To reflect the true diversity and evolutionary history of microorganisms
- To eliminate the need for laboratory testing
- To focus only on pathogenic species
A: To reflect the true diversity and evolutionary history of microorganisms
