Biological Classification
12 lessons 91 min 2 simulations
This chapter follows how the grouping of living things changed from Aristotle's trees, shrubs and herbs to Whittaker's five kingdoms, and why each change was made. It then walks through the three kingdoms made mostly of microbes, Monera, Protista and Fungi, gives a short sketch of Plantae and Animalia, and ends with the things the five kingdoms leave out: viruses, viroids, prions and lichens.
What the exam asks
NEET draws several questions a year from this chapter. Expect Whittaker's criteria and Table 2.1, the three kinds of archaebacteria, heterocysts and nitrogen fixers, diatom walls and diatomaceous earth, red tides, euglenoid pellicle, the four protozoan groups with their examples, coenocytic versus septate hyphae, the dikaryon, the four fungal classes with their spores and examples, viruses (Ivanowsky, Beijerinck, Stanley, capsid, RNA or DNA), the viroid (Diener, potato spindle tuber) and the phycobiont and mycobiont of lichens.
