cell biology : prokaryotes and eurkaryotes

• What are the two main types of cells discussed in the video?

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

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

  The genetic material, or DNA
• How is the genetic material organized in eukaryotic cells?

  It is enclosed in a nucleus
• What are the two additional features of animal and plant cells besides the nucleus?

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

  It acts as a barrier that controls what enters and exits the cell
• What type of cells are bacteria classified as?

  Prokaryotic cells
• What is a key characteristic of prokaryotic cells regarding their genetic material?

  The genetic material is not enclosed in a nucleus
• How do prokaryotic cells compare in size to eukaryotic cells?

  Prokaryotic cells are much smaller than eukaryotic cells
• What is the structure of the genetic material in bacteria?

  It consists 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 is important to remember about the bacterial cell wall?

  It is different from the plant cell wall
• What do prokaryotic cells contain besides the 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 larger; prokaryotic cells are smaller.
  • Eukaryotic cells have multiple linear chromosomes; prokaryotic cells have a single loop of DNA.
  • Prokaryotic cells may have plasmids; eukaryotic cells do not.
• What are the similarities between eukaryotic and prokaryotic cells?

  • Both have a cell membrane.
  • Both contain cytoplasm.
  • Both have genetic material (DNA).
• What resources can students use to practice questions on eukaryotic and prokaryotic cells?

  • Vision workbook
  • Online quizzes
  • Study guides
