Question

Given below are two statements: 
Statement I: Mycoplasma can pass through less than 1 micron filter size.
Statement II: Mycoplasma are bacteria with a cell wall.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both statement I and Statement II are correct
• B. Both statement I and Statement II are incorrect
• C. Statement I is correct but statement II is incorrect
• D. Statement I is incorrect but statement II is correct

Answer 1

The Correct Option is C

To determine the correctness of the statements, let's analyze each one:

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

Mycoplasmas are a type of bacteria known for lacking a cell wall, which makes them very small and flexible. They can indeed pass through filters with pore sizes less than 1 micron, a characteristic that distinguishes them from many other prokaryotes. Therefore, Statement I is correct.

Statement II: Mycoplasma are bacteria with a cell wall.

This statement is incorrect because a defining feature of mycoplasmas is that they lack a cell wall. This absence is what gives them high membrane flexibility and allows them to pass through small pores. Hence, Statement II is incorrect.

Considering the analysis of both statements, the correct choice is: Statement I is correct but statement II is incorrect.
