Question #46910
The Question
Standard taxonomic identification and binomial nomenclature heavily rely on consistent cellular morphology and cell wall chemistry. In this context, which of the following statements regarding Mycoplasma is INCORRECT?
Options
- A.
It is placed in Kingdom Monera based on its prokaryotic organization, despite lacking the characteristic cell wall used as a primary delineator.
- B.
Its natural insensitivity to penicillin is a direct consequence of lacking the structural indicator typical of most monerans.
- C.
It exhibits a highly stable cellular morphology due to the incorporation of sterols in its cell membrane, facilitating standard microscopic identification.
- D.
Its pleomorphic nature defies the rigid morphological criteria typically assumed for assigning a specific genus and species epithet.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often memorize that Mycoplasma lacks a cell wall but fail to connect this to its pleomorphism and the resulting taxonomic challenge.
The trap lies in the 'Common Half-Truth' of Option C: Mycoplasma does uniquely contain sterols in its membrane (an advanced fact), but this does not grant it a 'stable cellular morphology' comparable to walled bacteria.
