Question
Which of the following is true about bacteria?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Almost all bacteria possess both a cell membrane and a cell wall (with a few exceptions like Mycoplasma). Not all bacteria produce spores (only some genera like Bacillus and Clostridium), not all are aerobes (many are anaerobes or facultative), and while some are acidophiles, many grow best at neutral pH.
Hint
Consider the universal structural components found in nearly all bacterial cells.
