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.
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: Characteristic features of Phycomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes; Structure and reproduction of yeast and Mucor; Introduction and types of lichens. Three ways it is asked:

See the plansIntroduction 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.
Biodiversity: Unit Map and Reading Order
What the Biodiversity unit covers, how its nine questions spread over eleven chapters, and a reading order from classification to Nepal's medicinal plants.
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.
Algae: Green, Brown and Red, and the Conjugation of Spirogyra
Describe algal forms and reproduction, compare Chlorophyceae, Phaeophyceae and Rhodophyceae by pigment, food reserve, wall and flagella, and follow Spirogyra from spiral chloroplast to zygospore.
