Prokaryotic vs Eukaryotic

• All organisms are made of either prokaryotic or eukaryotic cells
• What are organisms with prokaryotic cells called?

  Prokaryotes
• Bacteria and archaea are prokaryotes.
• Organisms with eukaryotic cells are called eukaryotes
• What does a nuclear envelope enclose in eukaryotic cells?

  Genetic material
• Prokaryotic cells have a definite nucleus.

  False
• The region in a prokaryotic cell where DNA exists is called the nucleoid
• Prokaryotes were the first type of organism to evolve.
• What is believed to be the evolutionary origin of eukaryotes?

  Prokaryotes
• Organelles are tiny structures within the cytoplasm that perform specific jobs
• Prokaryotic cells contain many different types of organelles.

  False
• Match the cell type with its unique characteristic:

  Prokaryotic ↔️ Only ribosomes

  Eukaryotic ↔️ Multiple organelles
• Organelles are essential for prokaryotic cell function.

  False
• What is the primary function of ribosomes in both prokaryotic and eukaryotic cells?

  Protein synthesis
• Organelles in eukaryotic cells compartmentalize cellular functions
• Prokaryotes have a large surface area to volume ratio due to their small size.
• What advantage does the small size of prokaryotes provide?

  Nutritional efficiency
• All prokaryotes are unicellular organisms that lack a membrane-bound nucleus
• Eukaryotes can be unicellular or multicellular.
• What is the current evidence suggesting that some prokaryotes may exhibit multicellular characteristics?
