Which of the following bacteria are without a cell wall?
Correct answer: A. Mycoplasma
- A. Mycoplasma
- B. Gram positive bacteria
- C. Gram negative bacteria
- D. Archaeo bacteria
Explanation
Mycoplasma is indeed a bacterium that is known for lacking a cell wall. Unlike most bacteria, Mycoplasma species do not have a rigid cell wall composed of peptidoglycan. Instead, they have a unique cell membrane that provides shape and protection. This membrane contains sterols, which help maintain structural integrity. The absence of a cell wall makes Mycoplasma cells more flexible and pleomorphic (having various shapes).
