Biological Classification - NEET PYQ Set

How NEET Tests 'Biological Classification'

This is a high-yield, fully NCERT-based chapter that delivers 1-2 questions every year (a stable trend). From the previous-year papers, the reliably tested areas are:

• Kingdom Fungi - the four classes, their spore types (conidia, ascospores, basidiospores, zygospores), coenocytic vs septate mycelium, and examples (Rhizopus, Ustilago, Puccinia, Agaricus, Claviceps, Neurospora).
• Viruses / viroids / prions - who discovered what, RNA vs DNA, the viroid's free RNA (no protein coat), and prions causing mad-cow disease.
• Kingdom Monera - bacterial shapes, cyanobacteria, mycoplasma (no cell wall), archaebacteria.
• Kingdom Protista - identifying groups by their features (silica walls, red tides, pellicle, plasmodium) and examples.
• The five-kingdom system - Whittaker's criteria and ordering kingdoms by complexity.

Below are genuine NEET previous-year questions from this chapter, followed by exam-pattern practice in the same styles. Each has a full worked solution.
