Question: 142: Given below are two statements :
Statement I : Mycoplasma can pass through less than 1 micron filter size.
Statement I : Mycoplasma are bacteria with cell wall.
In the light of the above statements, choose the most appropriate answer from the options given below
(1) Statement I is correct but Statement II is incorrect
(2) Statement I is incorrect but Statement II is correct
(3) Both Statement I and Statement II is correct
(4) Both Statement I and Statement II are incorrect
Answer: Option (1)
Explanation:
Mycoplasma are the smallest free-living organisms and can pass through filters having pore size less than 1 micron.
This is because they are extremely small in size compared to other bacteria.
However, Mycoplasma lack a cell wall and possess only a plasma membrane.
Due to the absence of a rigid cell wall, they show pleomorphism and are resistant to antibiotics like penicillin that target cell wall synthesis.
Therefore, Statement I is correct, but Statement II is incorrect.
