Cell Theory and Cell Structure Practice Test
1. What are the three parts of the cell theory? a. All living things are made of cells b. Cells are the basic unit of life c. All cells come from pre-existing cells
2. Why is the cell theory considered a “theory” and not a “hypothesis”?
MANY scientists came together with MANY experiments
3. What are the structures that prokaryotes and eukaryotes share? a. DNA b. ribosomes c. Cell membrane d. Cytoplasm
4. Do all cells have a nucleus? ____ No _________ a. What is stored in the nucleus? _____ DNA _________________ b. What do we call cells that do have a nucleus? _____ Eukaryotic _____________________ c. What do we call cells that do not have a nucleus? _____ Prokaryotic ___________________ d. Which type of cell do you think the DNA is “easier” to gain access to?
____ Prokaryotic _________________ i. Why?
DNA is free floating in cytoplasm…do not have to get into nucleus
5. Do all cells have membrane-bound organelles? ___ No __________ a. What do we call cells that do have membrane bound organelles?
_____ Eukaryotic ____________________ b. What do we call cells that do not have membrane-bound organelles?
_______ Prokaryotic _______________
6. Identify the structures of the cell shown a. 1.
Cell membrane b. 2.
Vesicles c. 3. Golgi Bodies/Appartus d. 4. Ribosomes e. 5. RER f. 6. Nucleolus g. 7. Chromatin/DNA h. 8. Nuclear membrane/envelope i. 9. Nucleus j. 10. SER k. 11. Centrioles l. 12. Cytoplasm m. 13. Mitochondria n. 14. Lysosome
7. Is this an animal cell or plant cell? __ Animal…no CW, no chloroplasts, centrioles, no large vacuole _________

Write the letter of the structure for the description below:
8. K _____ Produces ATP for the cell
9. A _____ Jelly-like fluid that makes up most of the cell
10. _ B ____ Where photosynthesis occurs
11. _ J ____ The selective barrier of the cell
12. _ H ____ Stores water and provides support for the cell
13. __ D ___ Where the genetic material is stored
14. _ L ____ Rigid outer structure to protect the cell
15. __ G ___ Packages and sorts proteins
16. __ I ___ Contains digestive enzymes
17. _ F ____ Makes proteins for the cell; this version is floating in the cytoplasm
18. __ E ___ Canal connected to the nucleus; may or may not have ribosomes attached
19. _ C ____ Barrier that surrounds the nucleus
20. Is this an animal or a plant cell?
___ Plant…CW, no centrioles, chloroplasts, large vacuole __________________________________
NOTE: YOU WILL SEE PICTURES ON THE QUEST, BUT THESE ARE NOT THE EXACT SAME ONES!
NOTE: YOU SHOULD BE ABLE TO RECOGNIZE ALL STRUCTURES FOR A PLANT AND AN ANIMAL
CELL —NOT JUST THE ONES HERE
NOTE: YOU SHOULD BE ABLE TO PROVIDE THE FUNCTIONS FOR ALL STRUCTURES OF A
PLANT AND ANIMAL CELL —NOT JUST THE ONES HERE
21. What structure(s) do animal cells have that plant cells do not? centrioles
22. What structure(s) do plant cells have that animal cells do not? large central vacuole, cell wall, chloroplast
23. Let’s say a cell was making a protein for exporting out of the cell. What would the path be from start to finish for the cell parts involved? Some are provided for you a. DNA b. RER c. ribosomes d. Golgi Apparatus e. Vesicles f. Cell membrane
