Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Meristem culture
Concept:

Eradication of plant systemic viruses via shoot tip explant culture.

Solution:

The shoot apical meristem is continuously dividing and lacks functional vascular connections, making it free of systemic viruses. Culturing apical meristems yields virus-free plant lines.

Why other options are incorrect:

  • Protoplast fusion: Used to produce somatic hybrids between different plant species by fusing naked plant cells.


  • Anther culture: Used to generate haploid plants from microspores for plant breeding.


  • Callus culture: Cultures unorganized mass of parenchymatous cells; infected mother tissue transfers viral particles to the callus.

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.
