• Father of Classification • Assigned taxa, or groups

of related organisms• Binomial nomenclature

(two name naming system)• Homo sapiens

Please draw this diagram on the backside of your notes sheet. Draw a box around the three domains.

7

Kingdom Monera or Eubacteria

• Single celled• Prokaryotic• Make or absorb food• Cell wall

– peptidoglycan

8

Kingdom Archaea

• Single celled• Prokaryotic• Make or absorb food• DNA

– Similar to Eukaryotic

• Cell wall– Pseudopeptidoglycanor protein only

• Live in extreme environments

9

Kingdom Protista

• Single celled• Eukaryotic• Ingest or produce

food• No tissues or organs• Animal like—

consumers• Plant like—producers• Fungus like--

decomposers

10

Kingdom Fungi

• Multicellular• Eukaryotic• Cell wall

– Chitin

• Absorb food by breaking it down with enzymes– This is why we call

them decomposers

11

Kingdom Plantae

• Multicellular• Eukaryotic• Cell wall

– Cellulose

• Produce food– Photosynthesis

• Angiosperms: flowering plants

• Conifers: cone bearing

12

Kingdom Plantae

• Vascular • Grow tall • They have

distinctive body forms

• Tube like cells• Can transport

water to the leaves• Large roots • Ex: flowers, trees

• Non-Vascular • Do not grow off

the ground• Do not have a

water vascular system to transport water

• No roots• Ex: moss, lichen

13

Kingdom Animalia

• Multicellular• Eukaryotic• No cell wall• Ingest food• Motile
