Which field studies microscopic life forms such as bacteria and viruses?

• A. Microbiology
• B. Anatomy
• C. Botany
• D. Ecology

Answer: (A)

Studying microscopic life forms such as bacteria and viruses is microbiology. This field centers on organisms too small to see with the naked eye and explores their structure, function, genetics, growth, and roles in health, disease, and the environment. Anatomy focuses on the body’s tissues and organs, botany on plants, and ecology on how organisms interact with each other and their surroundings. Because microbiology specifically targets microorganisms, it is the best fit for questions about bacteria and viruses.
