Question

Which character is applicable to Mycoplasma?

• A. They pass through bacteria-proof filter paper.
• B. They are osmotically inactive.
• C. They require sterol for growth.
• D. All of the above.

Answer 1

Answer: (D)

All of the above.

Mycoplasma is the smallest bacteria which does not possess a cell wall and can pass through the bacteria-proof filter. Due to the presence of only cell membrane, they are osmotically inactive. They possess a cell membrane of sterols which does not help much in the maintenance of the osmotic conditions in the cell. In order to produce the cell membrane structure, the sterols are required.

Thus, the correct answer is option D.
