Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Permeable
Concept: The cell wall provides structural support but does not strictly regulate the passage of most small molecules and water.

Solution: Unlike the cell membrane, the primary cell wall is highly porous and fully permeable to water and most dissolved solutes.

Distractor Autopsy: Semi-permeable and differentially permeable are terms specifically reserved for the plasma membrane, which actively and passively selects what enters or exits the cell.

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.
