To grow; growth in a laboratory context is best described as what?

• A. Cultivation
• B. Culture
• C. Propagation
• D. Growth

Answer: (B)

In a laboratory setting, growth is described by the term culture. A culture is the population of cells or microorganisms that has been grown under controlled conditions, usually in a nutrient medium such as broth or on agar plates. This word specifically refers to the grown material—the organisms that have proliferated under the chosen environment and conditions.

Cultivation refers to the act or process of growing them, which is related but describes the procedure rather than the result. Propagation is more about producing additional organisms or increasing numbers, and growth is a general term that doesn’t name the material itself. So culture fits best because it names the actual grown population under lab conditions.
