Fungi can tolerate pH from____________?
Correct answer: C. 2-9
- A. 3-7
- B. 2-6
- C. 2-9
- D. 3-6
Explanation
Fungi generally tolerate acidic conditions and may grow across approximately pH 2 to pH 9, although their optimum is commonly in the acidic range. Students may choose b because pH 2 to pH 6 is a more typical preferred range, but it does not represent the full tolerance range given in standard texts.

The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
