Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Prokaryotic cell wall contains peptidoglycan
Concept: Chemical composition of the cell wall provides structural distinction between biological kingdoms.

Solution: A defining feature is that the prokaryotic (bacterial) cell wall is composed of peptidoglycan, a unique matrix of sugars and amino acids. In stark contrast, the fungal cell wall is composed of chitin.

Distractor Autopsy: Cellulose is found in plants. Silica is found in diatoms (protists). Cutin is a plant lipid.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
