Eukaryotes and Prokaryotes

• What is a key feature of both animal and plant cells?

  They have a nucleus
• What does the nucleus contain in eukaryotic cells?

  Genetic material (DNA)
• How is genetic material organized in eukaryotic cells?

  It is enclosed in a nucleus
• What are the two additional features of eukaryotic cells mentioned?

  Cell membrane and cytoplasm
• What is the function of the cell membrane?

  It encloses the cell and regulates entry
• What is the function of the cytoplasm?

  It contains organelles and facilitates chemical reactions
• What type of cells are bacteria classified as?

  Prokaryotic cells
• How is genetic material organized in prokaryotic cells?

  It is not enclosed in a nucleus
• What is a key difference in size between prokaryotic and eukaryotic cells?

  Prokaryotic cells are much smaller
• What does the genetic material of bacteria consist of?

  A single loop of DNA
• What are plasmids in prokaryotic cells?

  Small rings of DNA
• What additional structure do prokaryotic cells have besides the cell membrane?

  A cell wall
• What type of cell wall do prokaryotic cells have?

  Bacterial cell wall
• What do prokaryotic cells contain besides a cell membrane and cell wall?

  Cytoplasm
• What are the main differences between eukaryotic and prokaryotic cells?

  • Eukaryotic cells have a nucleus; prokaryotic cells do not.
  • Eukaryotic cells are generally larger than prokaryotic cells.
  • Eukaryotic cells contain multiple linear chromosomes; prokaryotic cells have a single loop of DNA.
  • Prokaryotic cells may have plasmids.
• What are the similarities between eukaryotic and prokaryotic cells?

  • Both have a cell membrane.
  • Both contain cytoplasm.
  • Both have genetic material (DNA).
