2.1.2 Prokaryotic cells

Cards (27)

  • In prokaryotic cells, the genetic material is located in the nucleoid
  • What are prokaryotic cells defined by?
    No true nucleus or organelles
  • Prokaryotic cells contain membrane-bound organelles.
    False
  • What is the cell wall of prokaryotic cells made of?
    Peptidoglycan
  • Eukaryotic cells contain membrane-bound organelles such as mitochondria
  • The cell wall of prokaryotic cells provides structural support and protection.

    True
  • What are the key features used to compare prokaryotic and eukaryotic cells?
    Nucleus, organelles, complexity
  • Where does cellular respiration occur in prokaryotic cells?
    Cytoplasm
  • Where is the genetic material located in prokaryotic cells?
    Nucleoid region
  • Prokaryotes may contain additional small, circular DNA molecules called plasmids
  • Prokaryotic cells have a true nucleus.
    False
  • In which organisms are prokaryotic cells found?
    Bacteria and archaea
  • Eukaryotic cells have a membrane-bound nucleus.

    True
  • What is the cell wall of prokaryotic cells made of?
    Peptidoglycan
  • What is the process called by which prokaryotic cells reproduce asexually?
    Binary fission
  • Match the cell type with the organism in which it is found:
    Prokaryotic cells ↔️ Bacteria
    Eukaryotic cells ↔️ Plants
  • Eukaryotic cells have a true nucleus with a membrane.

    True
  • Where is the genetic material located in prokaryotic cells?
    Nucleoid region
  • Prokaryotic cells lack membrane-bound organelles
  • The cell wall of prokaryotic cells is made of peptidoglycan
  • Prokaryotic DNA is typically a single, circular chromosome.

    True
  • The DNA in prokaryotes is a single, circular chromosome.

    True
  • What is the defining feature of prokaryotic cells in terms of cellular structure?
    No true nucleus
  • Match the feature with its description in prokaryotic cells:
    Nucleoid Region ↔️ Contains genetic material
    Organelles ↔️ No membrane-bound organelles
    Cell Wall ↔️ Made of peptidoglycan
  • Arrange the key differences between prokaryotic and eukaryotic cells:
    1️⃣ Nucleus: No true nucleus in prokaryotic cells
    2️⃣ Organelles: No membrane-bound organelles in prokaryotic cells
    3️⃣ Complexity: Prokaryotic cells are generally smaller and less complex
  • Prokaryotic cells lack a true nucleus, so their genetic material is located in the nucleoid
  • Where does cellular respiration occur in prokaryotic cells?
    Throughout the cytoplasm
