1.   __Organelle that contains the chromosomes in eukaryotic cells

2.____A specialized structure in the nucleus where components of ribosomes are made

3.___The membrane in eukaryotic cells that encloses the nucleus, separating it from the cytoplasm

4.___ The organelles where cellular respiration occurs

5. ____ The exterior phospholipid bilayer of every cell that acts as a selective barrier

6. __ An organelle in eukaryotic cells consisting of stacks of membranes that modify, store and route products of the endoplasmic reticulum.  The “post office” of the cell

7. __Organelle in plants and photosynthetic protists where photosynthesis occurs

8. ____A protective layer external to the plasma membrane in plant cells composed of cellulose that provides stiffness to the cell.

9.  ___Structure in the cell that is responsible for protein synthesis

10. ____ An extensive labyrinth of sacs connected to the nuclear envelope that is studded with ribosomes that produce protein

11. ____A network of microtubules, microfilaments, and intermediate filaments that branch throughout the

  cytoplasm and serve a variety of mechanical and transport functions.

12. __ __A membrane bound sac that takes up most of the interior of a mature plant cell.  Contains water and other solutes.

13. __ __ Membranous network of tubular structures that synthesize lipids and detoxify the cell

14. __ __a membrane-enclosed sac of digestive enzymes found in the cytoplasm of eukaryotic cells

15. __ __ A dense region of DNA in a prokaryotic cell that lacks a membrane bound nucleus

16. __ __ Structures external to the cell that aid in movement.  Composed of microtubules

17.  What is the Cell Theory?

18.  List four differences between prokaryotic and eukaryotic cells

19.  List two organelles found in plant cells and not in animal cells.

20.  What two cellular structures are found in ALL types of cells?

21.  What is the cytoskeleton of the cell?  Why is it important?

22.  How does cellular makeup correlate to the cell’s function?
