Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Cyclosis
Concept: Organelles do not propel themselves; they are carried by the flow of the cytoplasm.

Solution: Cyclosis (or cytoplasmic streaming) is the active, continuous circular movement of the cytoplasm driven by actin microfilaments. This movement sweeps organelles like mitochondria and chloroplasts around the cell to distribute nutrients and oxygen evenly.

Distractor Autopsy: Endoplasmic streaming is not a standard biological term. The Golgi and tRNA have no locomotive function.

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.
