Eukaryotes and Prokaryotes

• What is a eukaryotic cell?


  cell with a nucleus
• Examples of eukaryotic cells

  plant, animal and fungal cells
• What is a prokaryotic cell?


  A cell without a nucleus
• Example of a prokaryotic cell


  bacteria
• Which cell is smaller out of prokaryotic and eukaryotic cells?


  Prokaryotic cells
• How is genetic material stored in a prokaryotic cell?


  In a single DNA loop, there may be one or small rings of DNA called plasmids
• What are small rings of DNA called?

  Plasmids
• What are plasmids?


  Small rings of DNA
• Where is the genetic information stored in a eukaryotic cell?

  A nucleus
• What are the two main types of cells in biology?

  Eukaryotic and prokaryotic cells
• What are the key differences between eukaryotic and prokaryotic organisms?


  • Eukaryotic organisms can be unicellular or multicellular; prokaryotic organisms are almost always unicellular.
  • Eukaryotic organisms are more complex and can form specialized tissues and organs; prokaryotic organisms are simpler.
  • Eukaryotic organisms include animals, plants, fungi, and protists; prokaryotic organisms include bacteria and archaea.
• How do prokaryotic cells compare to eukaryotic cells in terms of structure?


  Prokaryotic cells are much simpler in structure than eukaryotic cells.
• Why do scientists believe that prokaryotic cells developed before eukaryotic cells?


  Because prokaryotic cells are simpler in structure than eukaryotic cells.
