Question Detail
Question
Which of the following is true about bacteria?
Correct Answer
Option B is the correct answer.
Detailed Explanation
All bacteria possess both a cell membrane and a cell wall (with very few exceptions like mycoplasmas). Not all bacteria grow best at acidic pH (many prefer neutral), not all produce spores, and not all are aerobes (many are anaerobes or facultative anaerobes).
Hint
Consider the universal structural components found in almost all bacterial cells.
