Which term refers to 'Bacteria that require oxygen to grow'?

• A. Aerobes
• B. Anaerobes
• C. Microbes
• D. Bacteria

Answer: (A)

Bacteria that require oxygen to grow are described as aerobes. This term identifies organisms that rely on oxygen for energy production, typically using aerobic respiration where oxygen acts as the final electron acceptor in the electron transport chain. This pathway yields more energy and supports growth in oxygen-rich environments. The other terms don’t fit as precisely: anaerobes are those that do not require oxygen (or are harmed by it); microbes is a broad category that includes many different organisms; bacteria is a general group that can include both aerobes and anaerobes. So aerobes is the precise term for bacteria that need oxygen.
