Cells : Prokaryote vs Eukaryote

Cells : Prokaryote vs Eukaryote. Cells have evolved two different architectures:. Prokaryote “style” Eukaryote “style”. Prokaryote cells are smaller and simpler. Commonly known as bacteria 10-100 microns in size Single-celled(unicellular) or Filamentous (strings of single cells).

  1. Cells: Prokaryote vs Eukaryote

  2. Cells have evolved two different architectures: • Prokaryote “style” • Eukaryote “style”

  3. Prokaryote cells are smaller and simpler • Commonly known as bacteria • 10-100 microns in size • Single-celled(unicellular) or • Filamentous (strings of single cells)

  4. These are prokaryote E. coli bacteria on the head of a steel pin.

  5. Prokaryote cells are simply built (example: E. coli) • DNA is free floating • Does not have a nucleus

  6. Prokaryote cells are simply built (example: E. coli) • 1st cells/ primitive

  7. Prokaryote lifestyle • unicellular: all alone • Bacteria Kingdoms • Archaebacteria • Eubacteria

  8. Eukaryotes are bigger and more complicated • Have a nucleus • can be multicellular • DNA (genetic instructions) is in the nucleus.

  9. Organelles are membrane-bound cell parts • Mini “organs” that have unique structures and functions • Located in cytoplasm

  10. Eukaryote cells can be multicellular • include animal, plant, fungi, and protist cells

  11. Prokaryotes Eukaryotes simple and easy to grow can specialize fast reproduction tend to be multicellular (some exceptions) all the same can build large bodies Advantages of each kind of cell architecture
