Match each group from viruses to angiosperms with what it gives or costs people, with Nepal's own examples — yarsagumba, chiraito, niguro, khote salla, sal, lokta and large cardamom.
Unit 2 carries 9 of the 40 botany marks; with eleven chapters sharing them, this one averages under one (MEC publishes weights by unit, not by chapter). The MEC scope line: Economic importance of viruses, bacteria, blue-green algae, fungi, algae, bryophytes, pteridophytes, gymnosperms and angiosperms of Nepal. It is asked three ways:
The organisms themselves are described in the unit's earlier chapter notes; the five medicinal species are in Medicinal plants of Nepal.

What the Biodiversity unit covers, how its nine questions spread over eleven chapters, and a reading order from classification to Nepal's medicinal plants.
Introduction to Classification: From Two Kingdoms to Three Domains
Say why the two-kingdom system failed, rank a plant from kingdom to species with the right suffixes, write a binomial correctly, and tell Whittaker's five kingdoms from Woese's three domains.
Monera and Virus: Bacterial Cells, Blue-green Algae and the Virion
Label a bacterial cell and explain the Gram stain, classify bacteria by shape, flagella and nutrition, read a growth curve, describe a heterocyst, and compare TMV with a T4 phage and a lytic with a lysogenic cycle.
Fungi and Lichens: Four Classes, Yeast, Mucor and the Dual Organism
Compare the four classes of fungi by hyphae and spores, follow budding and ascospores in yeast and sporangia and zygospores in Mucor, and name the partners, growth forms and uses of lichens.
