Six Kingdoms of Life Notes

Georgia Performance Standards
SB3b. Compare the structure and functions between the six kingdoms (archaebacterial, eubacteria, Protista, fungi, Animalia, & Plantae.
Archaebacteria
Domain: Archae
Prokaryote
Unicellular
Heterotrophs or Autotrophs
Cell Walls of peptido-glycan
Examples:
  • Halophiles
  • Thermophiles
Live in extreme environments, such as extremely salty lakes or extremely hot deep ocean vents
Probably some of the first living things on earth.

Habitats
Eubacteria
Domain: Bacteria
Prokaryote
Unicellular
Heterotroph or Autotroph
Cell Walls that do NOT have peptidoglycans
Examples: S. aureus, E. coli
Live in almost all environments. Commonly found in soil.
The most numerous organisms on Earth - a group from the University of Georgia estimates the number to be five million trillion trillion - that's a five with 30 zeroes after it!

Protista
Domain: Eukarya
This is the kingdom for anything that doesn’t fit in the other 5 kingdoms.
All are eukaryotes
Most are unicellular, some are colonial, some are multicelluar
Some are heterotrophic, some are autotrophic
cell walls of cellulose in some
Examples: amoeba, slime molds, giant kelp
Carageenan, a substance extracted from some protists, is used as a thickening agent in ice cream and other foods.

Plantae
Domain: Eukarya
Eukaryotic
All are multicellular
All are autotrophic – make their own food using sunlight through the process of photosynthesis
Cell Walls of Cellulose
Examples: mosses, ferns, trees
One of the oldest living things on Earth is a tree that is almost 5000 years old – that’s older than the pyramids in Egypt.
Habitats: All around you wherever they can obtain light, carbon dioxide, and water to go through the process of photosynthesis.
Fungi
Domain: Eukarya
Eukaryote
Most are Multicellular some are Unicellular
Heterotroph – break down other organisms
Cell Walls of chitin
Examples:
  • Mushrooms
  • Yeast that we use to make bread rise
Used to make many products, such as bread, citric acid for
Habitats:

Animalia
Domain: Eukarya
Eukaryotic
All are multicellular
All are heterotrophic – must eat other organisms
  1. No cell walls

Examples: insects, fish, worms, mammals
Insects are some of the most numerous animals - For each person there are about 200 million insects.

Habitats: You know many places all over the Earth that these species live, pick.
