Which device is used to culture cells or produce useful substances in a controlled environment?

• A. Bioreactor
• B. Tissue
• C. Culture
• D. Organism

Answer: (A)

This is about the device used to culture cells or produce useful substances in a controlled environment. A bioreactor is designed to provide precise, adjustable conditions—temperature, pH, oxygen levels, nutrients, agitation, and sterile conditions—so cells can grow efficiently and produce useful products like proteins or vaccines on a larger scale. It differs from tissue, which is a living collection of cells forming structures; culture, which is the process or material being grown; and organism, which is a living individual. The key idea is that a bioreactor supplies and controls the environment needed for reliable, scalable cultivation and production.
