Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Starch
Concept:

Plants require massive, insoluble energy reserves to fuel the germination of their offspring before they can grow leaves and photosynthesize.

Solution:

  • The universal energy storage polysaccharide of the entire plant kingdom is Starch.


  • Plants pack massive quantities of starch granules into their grains (wheat, rice, corn) and seeds, ensuring the embryonic plant has a massive, slow-release energy source to rely on during early underground growth.


Why other options are incorrect:

  • Glycogen: The storage polysaccharide of animals (liver/muscle), never found in plants.


  • Pectin: A structural gel-like carbohydrate found in the cell walls (makes jams set), not the primary bulk energy storage.


  • Dextrin: A short, broken-down fragment of starch, not the naturally stored bulk molecule itself.

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.
