• - extremophiles

9
KINGDOM PROTISTA

• -heterotrophic/autotrophic eukaryotes
• -unicellular or multicellular (kelp)

10
KINGDOM FUNGI

• Heterotrophic eukaryotes
• Absorb nutrients from surroundings
• EX. Yeast, mold and mushrooms, athletes foot

11
KINGDOM PLANTAE

• Multicellular eukaryotic plants
• Mostly autotrophic and photosynthetic
• EX. Mosses, ferns, conifers, flowering plants

12
KINGDOM ANIMALIA

• Eukaryotic
• All multicellular
• Heterotrophic

13
SYSTEMATICS

• Classify organisms based on natural traits
• Uses similarities in appearance, embryos,
  chromosomes, proteins, and molecular molecules
  (DNA RNA)

14
PHYLOGENETICS

• Based on evolutionary history
• Common ancestors

15

• Uses chromosomes and molecular molecules such as
  DNA, RNA, and proteins

16
CLADISTICS

• Uses shared or derived characteristics unique to
  a taxon/group (I.E. feathers unique to birds)
