Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Symplast
Concept:

Water and solutes can move through plant tissues via different pathways: the apoplast (non-living spaces) and symplast (living contents).

Formula:

None

Solution:

  • The symplast pathway involves water moving from cell to cell through the cytoplasm.


  • The cells are connected by microscopic channels called plasmodesmata, which facilitate this direct cytoplasmic transport.


Why other options are incorrect:

  • Apoplast: Movement through cell walls and intercellular spaces, not plasmodesmata.


  • Vacuolar: Movement across vacuoles, which involves crossing tonoplast membranes.

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.
