Question

Which one of the following statements about mycoplasma is wrong?

• A. They are also celled PPLO
• B. They are pleomorphic
• C. They are sensitive to Penicillin
• D. They cause diseases in plants

Answer 1

The correct option is C They are sensitive to Penicillin

• Penicillin class drugs work by indirectly bursting bacterial cell walls. They do this by acting directly on the cell wall, which plays an essential structural role in bacterial cells.
• But, Mycoplasma does not have a cell wall. Thus, Penicillin can not act on the mycoplasma. So, mycoplasma is not sensitive to penicillin.

So, the correct answer is 'They are sensitive to penicillin'.
