Eukaryotic cells

• Have a nucleus and organelles

• Do not have a nucleus and organelles

• Divide very quickly

• Make up only single celled organisms

The cell spends the majority of its life in

• Interphase

• Mitosis

• Cytokinesis

• None of these

Which is true of prokaryotic and eukaryotic cells?

• Prokaryotic cells are larger than eukaryotic cells.
• Eukaryotic cells do not have nucleus, and prokaryotic cells do have nuclei.
• Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.
• Eukaryotic cells are simpler than prokaryotic cells.

Examine the cell diagrams shown. Which of the following choices identifies the eukaryotic cell for the correct reason?

• Cell A, because it is a single cell
• Cell A, because a nuclear membrane contains the cell’s DNA
• Cell B, because it is much smaller
• 
  Cell B, because it contains genetic material

What do all of these organisms have in common?
