2. This organelle is made of a _____ bilayer and what large

structures?

3. What is the function of those large structures?

4. Cell membranes are _____ _____ because they only let certain

molecules in and out of the cell.

5. Look at the following diagram, why do you think cells need to be small and not large?

These two cells are soaked in nutrients.

The nutrients soaked in one mm thick.

6. What structure is found in a bacterial cell and plant cell, but not

an animal cell?
