1. Cells Review Sheet
I. Reviewing Key Concepts: On the lines provided, complete the following sentences.
1. All ____________________ are composed of cells.
2. Cells are the basic units of ____________ and ____________ in all organisms.
3. New cells are produced from __________________.
4. The cells of eukaryotes have a(an) ____________ ; the cells of _____________do not.
5. Eukaryotic cells also have a variety of specialized structures called _____________.
LIVING THINGS
STRUCTURE
FUNCTION
EXISTING CELLS
NUCLEUS
PROKARYOTES
ORGANELLES

2. II. Reviewing Key Skills: Label each cell as either prokaryotic or eukaryotic.
PROKARYOTES
6. _________________ _________________
EUKARYOTES

3. 8. Comparing and Contrasting: Explain the similarities and differences between a prokaryotic cell and a eukaryotic cell.
____________________________________________________________
9. Applying Concepts: Are human cells prokaryotic or eukaryotic? Explain your answer.
PROKARYOTIC
HAVE only a few ORGANELLES
HAVE NO NUCLEUS
PRIMITIVE CELLS
ONLY BACTERIA
EUKARYOTIC
HAVE ORGANELLES
HAVE NUCLEUS
MODERN CELLS
All other living things.
*ALL CELL TYPES HAVE CELL MEMBRANES, CYTOPLASM & DNA.
EUKARYOTIC – BECAUSE THEY CONTAIN A NUCLEUS.

4. III. Word Bank Matching: Match the structure with its function in the cell.
a. cell wall, b. nucleus, c. cytoskeleton, d. endoplasmic reticulum,
e. Golgi apparatus, f. chloroplast, g. mitochondrion,
____ 10. controls most cell processes and contains DNA
____ 11. uses energy from food to make high-energy compounds
____ 12. provides support and protection for the cell
____ 13. maintains cell shape with a network of protein filaments
____ 14. uses energy from sunlight to make food molecules
____ 15. site where lipid components of the cell membrane are assembled and where
proteins are chemically modified
____ 16. modifies, sorts, and packages proteins and other materials from the ER B G A C F D E

5. IV. Reviewing Key Skills:
17. Inferring: Plants have cells that contain chloroplasts. Why must their cells contain mitochondria as well?
___________________________________________________________________
Chloroplasts make nutrients (food) through photosynthesis. Mitochondria perform cellular respiration by taking nutrients from the cell and turning it into energy.

6. 18. Using Analogies: In some ways, a cell is analogous to a factory
18. Using Analogies: In some ways, a cell is analogous to a factory. Create an analogy describing the job of a lysosome within a cellular “factory.”
___________________________________________________________________
Cell Membrane – security
Nucleus- Supervisor
Mitochondria- power source
Golgi- packaging & deliveries
Lysosome- custodial crew
Vacuoles- warehouse
Cytoskeleton- building frame
Ribosomes- product (what you make)
ER- assembly
Cytoplasm- factory floor

7. 19. Comparing and Contrasting: What structures make plant and animal cells different?
___________________________________________________________________
Plant cells- Chloroplasts, cell wall, chlorophyll
