Bacteria, Protists, Fungi

Taxonomy is changing
 DNA technology is showing
relationships previously not
known

You will hear the term “clade” –
what does that mean?
 Clade – any taxon that
consists of all the
evolutionary descendants of
a common ancestor
 Identified by picking any
point on a phylogenetic
tree and tracing all the
descendant lineages

Binomial Nomenclature, Scientific Name

Genus species or Genus species
 Genus is capitalized, species is lowercase
 Italicized or underlined
 Homo sapiens
 Tursiops truncatus

Start on Scanning objective,
look for color
Center and focus
Move to the 10x objective
Center and focus
Move to the 40x objective
Center and focus
If necessary, move to oil
immersion
 Place drop of oil on slide and
move oil lens into the oil
 DO NOT get oil on any of the
other lenses
 Be sure to WIPE oil off of lens
when done!!!!! (with lens paper!)
