Q.

Given below are two statements :

Statement I : Mycoplasma can pass through less than 1 micron filter size.

Statements II : Mycoplasma are bacteria with cell wall. In the light of the above statements, choose the most appropriate answer from the options give below :

  1. A

    Both Statement I and Statement II are correct

  2. B

    Both Statement I and Statement II are incorrect

  3. C

    Statement I is correct but statement II is incorrect

  4. D

    Statement I is incorrect but Statement II is correct

Solution

Mycoplasmas are the smallest known free-living organisms, with sizes around 0.2-0.3 micrometres. They readily pass through standard 0.22 micron filters used to sterilise solutions. Statement I is correct.

The defining feature of mycoplasmas is the absence of a cell wall, which makes them resistant to penicillin-class antibiotics that target wall synthesis. Statement II is incorrect.
