SBI3U Diversity of Living Things Review Sheet
Use the following topics as a GUIDE to help you study for your Unit 1 Diversity of Living Things Test which will occur
Wednesday, September 30th. Remember to go through your homework and use your notes as your main source of
information (unless you were asked to summarize some pages of the textbook yourself).
Diversity Topics:
Chapter 1 – Species Classification
 3 Species Concepts – how to apply each one
 Taxonomy: know the various taxons in order, and be able to compare organisms described using these taxons,
how to write them properly
 Importance of a phylogenetic tree – be able to create one
 Dichotomous key – purpose, practicality, issues with it
 Difference between the two major cell types (prokaryotic and eukaryotic)
 Types of biodiversity – and why it is important
 Main characteristics that differentiate the Six Kingdoms (see Table 1.5 on p. 29)
Chapter 2 – Microscopic Diversity
 Viruses: general characteristics and replication (lytic & lysogenic cycles) - what is a capsid? prion? provirus?
 Kingdom Bacteria & Archaea: morphology, nutrition, habitats, reproduction – what is an aggregation?
endospore? cyanobacteria?, extremophiles (3 types) vs. mesophiles, binary fission, conjugation
 Kingdom Protista: general characteristics (3 types) – animal-like, fungus-like, and plant-like protists, what is a red
tide?
Chapter 3 – Multicellular Diversity
 The evolution from algae to terrestrial plants – what evidence might lead some scientists to place green algae in
the plant kingdom?, 2 types of vascular plant tissue (xylem and phloem) – function of each, the basic structure of
a brown alga – function of holdfast, stipe, and blade
 Kingdom Plantae: non-vascular plants (bryophytes) – what are rhizoids?, vascular plants (gymnosperms and
angiosperms)
 Kingdom Fungi: structure of a fungi – function of hyphae, fruiting body, and mycelium, nutrition, reproduction
methods (budding vs. fragmentation) – what is a lichen?
 Kingdom Animalia: characteristics – levels of organization, body layers (what are they?), symmetry and body
plans, body cavity, segmentation, movement and reproduction – what is radial symmetry? coelom?
