Terminology
Terminology

  • Terminology is not the focus of this course

  • You need to learn some basic terms: those in lab exercises and lecture notes

  • “Taxa”: remember the phyla, (classes), and representative genera I introduce in lecture

  • Do not remember all the bold-faced terms in the text

    • (although it might be nice for you to know them when you read the text – See Starr & Taggart Glossary)

  • Watch the references to chemistry and cells

    • (review chapters on chemistry and cells)



How many species are there
How many species are there?

Thousands of described species per phylum

Data from World Resources Institute

Total = 1,381 thousand



Six kingdoms defined

The six “kingdoms”

Bacteria

Archaea

Protista

Plants

Fungi

Animals

Simple diagnostic characters won’t always classify every organism into its proper kingdom

Prokaryotic / eukaryotic

Cell arrangement

Metabolism of carbon (autotrophs or heterotrophs?)

The number of kingdoms is debatable

Six Kingdoms defined

– in Domain Bacteria

– in Domain Archaea

}

in Domain Eukarya
