Which term describes single-celled microorganisms with varied effects?

• A. Bacteria
• B. Fungi
• C. Immunity
• D. Microorganism

Answer: (A)

Single-celled microorganisms with varied effects are described by bacteria. Bacteria are single-celled, prokaryotic organisms that come in different shapes and occupy almost every environment. Their effects vary widely: many bacteria are beneficial, such as those aiding digestion or fermentation, while others are pathogenic and can cause infections if they enter the body or skin. In contrast, fungi are mostly multicellular (though some yeasts are single-celled), immunity is the body's defense system, and a microorganism is a broad term that includes organisms beyond just single-celled bacteria. So, the best match for a term describing single-celled microorganisms with varied effects is bacteria.
