TWO GROUPS
• Prokaryotes (P)
• Eukaryotes (E)
• Two groups broken into three
domains based on comparison of
rRNA sequences

CLASSIFICATION (pg 349)
KINGDOM EUBACTERIA
-unicellular prokaryotes
-true bacteria
KINGDOM ARCHEABACTERIA
-unicellular prokaryotes
-chemosynthetic
- extremophiles
KINGDOM PROTISTA
-heterotrophic/autotrophic
eukaryotes
-unicellular or
multicellular (kelp)
KINGDOM FUNGI
- Heterotrophic
eukaryotes
- Absorb nutrients from
surroundings
EX. Yeast, mold and
mushrooms, athlete’s
foot
KINGDOM PLANTAE
- Multicellular eukaryotic plants
- Mostly autotrophic and photosynthetic
EX. Mosses, ferns, conifers, flowering plants

SYSTEMATICS
• Classify organisms based on natural traits
• Uses similarities in appearance, embryos,
chromosomes, proteins, and molecular
molecules (DNA & RNA)
PHYLOGENETICS
• Based on
evolutionary
history
• Common
ancestors
• Uses chromosomes and molecular
molecules such as DNA, RNA, and
proteins
CLADISTICS
• Uses shared or derived
characteristics unique
to a taxon/group (I.E.
feathers unique to
birds)
Homework
• Worksheet with cladiogram
