Question

What is incorrect about Mycoplasma?

• A. They are osmotically inactive.
• B. They show absence of cell wall.
• C. They are insensitive to modern antibiotics.
• D. They are obligate intracellular parasites.

Answer 1

Answer: (D)

They are obligate intracellular parasites.

Mycoplasma is the smallest bacteria which does not possess a cell wall. Due to the presence of only cell membrane, they are osmotically inactive. Most of the antibiotics target the cell wall structure. This is the reason which renders the organism to be insensitive to the modern antibiotics. They can be parasitic or saprophytic.

Thus, the correct answer is option D.
