  • Which structure is unique to eukaryotic cells? DNA, cell membrane, ribosomes, nucleus
    Nucleus is unique to eukaryotic cells.
  • Which structure is common to plant and animal cells?
    Both plant and animal cells have a cell membrane, nucleus, and various organelles.
  • What is the basic unit of life?
    The cell is the basic unit of life.
  • What is the main difference between prokaryotic and eukaryotic cells?
    Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
  • What are the three parts of the cell theory?
    1. All living organisms are composed of cells. 2. The cell is the basic unit of life. 3. All cells arise from pre-existing cells.
  • How are plant and animal cells different?
    Plant cells have a cell wall and chloroplasts, while animal cells do not.
  • What clue can tell you if a cell is prokaryotic or eukaryotic?
    Presence of a nucleus indicates a eukaryotic cell; absence indicates a prokaryotic cell.
  • What is a difference between prokaryotic and eukaryotic cells?
    Prokaryotic cells have circular DNA, while eukaryotic cells have linear DNA.
  • Which organisms are eukaryotes? Animals, plants, archaea, fungi
    Animals, plants, and fungi are eukaryotes.
