Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Bacteria
Concept: Cell wall composition is a major taxonomic identifier across the domains of life.

Solution: The cell wall of bacteria is uniquely constructed from peptidoglycan (also called murein), a complex polymer of sugars and amino acids that forms a massive, mesh-like sacculus around the cell.

Distractor Autopsy: Plants and most algae use cellulose. Fungi use chitin.

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.
