prokaryotic and Eukaryotic cells

• What are the key features of prokaryotic cells?

  • No nucleus
  • Genetic material (nucleoid) is not enclosed by a nuclear membrane
  • Typically have a cell wall
  • Some may have a capsule
  • May have flagella
  • Ribosomes are present

  
• What are the key features of eukaryotic cells?

  • Have a nucleus enclosed by a nuclear membrane
  • Contains nucleolus
  • Cell membrane present
  • Endoplasmic reticulum present
  • Ribosomes are present
  • May contain chloroplasts (in plant cells)
  • Golgi apparatus present
  • Mitochondria present
  • Cytoplasm present

  
• Which type of cell has a cell wall in some organisms?

  Eukaryotes

  
• Which type of cell may have a capsule?

  Prokaryotes

  
• What structure aids in prokaryotic movement?

  Flagellum

  
• What is the main structural difference between prokaryotic and eukaryotic cell membranes?

  The main difference is the presence of membrane-bound organelles in eukaryotes, while prokaryotes do not have such organelles.

  
• Where is the nucleolus located in a eukaryotic cell?

  Inside the nucleus

  
• Which organelle in eukaryotic cells is responsible for photosynthesis?

  Chloroplast

  
• What organelle modifies and packages proteins in eukaryotic cells?

  Golgi apparatus

  
• Which organelle is responsible for cellular respiration in eukaryotic cells?

  Mitochondrion

  
• What are the key differences in organelle presence between prokaryotic and eukaryotic cells?

  • Nucleus: Absent in prokaryotes, present with nuclear membrane in eukaryotes
  • Endoplasmic reticulum: Absent in prokaryotes, present in eukaryotes
  • Golgi apparatus: Absent in prokaryotes, present in eukaryotes
  • Mitochondria: Absent in prokaryotes, present in eukaryotes
  • Chloroplasts: Present only in some eukaryotes

  
• What are prokaryotic cells lacking?

  A nucleus and membrane-bound organelles
• Where is the genetic material located in prokaryotic cells?

  In a region called the nucleoid
• What types of organisms are typically prokaryotic?

  Bacteria and archaea
• How do eukaryotic cells differ from prokaryotic cells?

  Eukaryotic cells have a nucleus and organelles
• What is a defining feature of eukaryotic cells?

  A nucleus enclosed by a nuclear membrane
• What types of organisms can be eukaryotic?

  Unicellular and multicellular organisms
• What are the key structural differences between prokaryotic and eukaryotic cells?

  • Prokaryotes: No membrane-bound organelles, no true nucleus, typically have a cell wall, capsule sometimes present.
  • Eukaryotes: Multiple membrane-bound organelles, true nucleus with nuclear membrane, cell wall present in plants/fungi/bacteria only, capsule never present.
• If a cell has no true nucleus and no membrane-bound organelles, what type of cell is it?


  Prokaryotic cell
• Where is the genetic material located in eukaryotic cells?

  In the nucleus
• What is the structure of genetic material in prokaryotes?
