2.  Mr. Wood is creating an analogy between a community in an ancient castle and cell organelles and their functions.  Which of the following analogies be most appropriate for Organelle B?  

• Organelle B is most like a king because he directs the functions of his castle.

• Organelle B is most like a gatekeeper because he controls what enters and leaves the cell.

• Organelle B is most like a guard because he protects the castle.

• Organelle B is most like a cook because he makes food for the castle.

4.  Mark is trying to construct an argument that states that the cell illustrated is prokaryotic.  Which of the following statements MUST be included in his argument?  

• The cell in the illustration lacks chloroplasts.

• The cell in the illustration has no membrane-bound organelles.

6.  Why can't the cell in the picture below be a plant cell?  (Select two).  

• The cell in the picture isn't green, and plant cells are always green.

• The cell in the picture has no chloroplasts, so it can't conduct photosynthesis like plants.

• The cell has no membrane bound organelles, so it isn't eukaryotic like plant cells.

• The cell in the picture has no cell wall, so it isn't as well-protected as a plant cell would be..
