Prokaryotes and eukaryotes key

  1. 1. Prokaryotes and Eukaryotes Notes
  2. 2. Two main types of cells… 1.Prokaryotes 2.Eukaryotes
  3. 3. The Diversity of Life Begins with simple prokaryotic cells complex eukaryotic cells Ends with
  4. 4. The Six Kingdoms Prokaryotic Eukaryotic 1. Eubacteria (Monera) 1. Animals 2. Archaebacteria 2. Plants 3. Fungi 4. Protista
  5. 5. Prokaryotes (pro = before, karyote = nucleus  before there was a nucleus) • The Earth’s first living things • The simplest life forms exhibiting (showing) cellular structures • The Earth’s most abundant inhabitants
  6. 6. Prokaryotes • Prokaryotes can survive in a wide range of environments – can withstand extreme temperatures – extreme pH levels – can live in areas of no oxygen or no water • obtain their energy in a variety of ways -some can make their own food (autotrophs) -some have to find their food (heterotrophs)
  7. 7. Archaebacteria
  8. 8. Hot Spring (Yellowstone National Park)
  9. 9. Hot Spring (Yellowstone National Park)
  10. 10. Boiling Mudpot: Lassen Volcanic National Park, California
  11. 11. Volcano
  12. 12. Antarctica
  13. 13. Prokaryotes Prokaryotic cells exist in two major kingdom: – Eubacteria (Monera) • Most of the common bacteria that are found everywhere – Archaebacteria (archae=ancient or old) • Ancient bacteria that live in very extreme conditions only found in certain places on Earth.
  14. 14. Eukaryotes (eu = true, karyote = nucleus  they have a real or true nucleus) • Eukaryotes arose from prokaryotes and developed into larger and more complex organisms. • Examples include some unicellular protists to multicellular fungi, plants, and animals. • HINT: Remember YOU are a EUKARYOTE!
  15. 15. Age • Prokaryotes: Older- 3.5 billion yrs • Eukaryotes: Younger- 1.5 billion yrs
  16. 16. Cell Size • Prokaryotes: very,VERY small • Eukaryotes: very small to large
  17. 17. Covering around genetic material and other cell parts • Prokaryotes: no membrane covering around the genetic material (DNA) and other cell parts • No Nucleus • Eukaryotes: – membrane-bound nucleus (with DNA) and other membrane-bound cell parts.
  18. 18. Cell parts • Prokaryotes: –Only a few types of cell parts –Simple • Eukaryotes: –Many different cell parts –Complex
