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

Why is the nucleus important? 

• It give the cell its energy
• It stores genetic information
• It uses sunlight for food
• It makes the proteins
