5. City Limits Cell Membrane
A thin flexible covering that surrounds the cell
Controls what goes in and out of the cell
Controls what goes in and out of a city
Return to City
Return to cell

6. Road System Endoplasmic Reticulum
Allows for movement throughout the city
A network of tube-like passageways through which proteins from the ribosomes are transported
Return to City
Return to cell

7. City Hall Nucleus Controls all the activities of the city
A large, round/oval structure near the center of the cell that controls all of the activities in the cell
Return to City
Return to cell

8. City Auditor Chromosomes
Stores all the records of the city and passes them on as the city grows
Rod-shaped bodies found in the nucleus that pass on hereditary traits
Return to City
Return to cell

9. City Planning Ribosomes
Place in city hall where plans are made for the construction of the city
Grain-like bodies made of RNA in the nucleolus where proteins are produced
Return to City
Return to cell

10. Food Processing Lysosomes Plant
Processes large quantities of food entering the city into smaller packages that can be used more easily
Small, round structures in the cytoplasm
Contain digestive enzymes to break down large food into sugars

Return to cell

11. Warehouse Vacuole A large round sac in the cytoplasm
Stores water, food, wastes
Stores materials needed by the city
Return to City
Return to cell

12. Construction Nucleolus Company
Builds structures
for the city
Small dense object found in the middle of the nucleus
Makes RNA for the cell
Return to cell
Return to city

13. Delivery Van Cytoplasm
Delivers products made at the construction company to other locations in the city
Jelly-like;
Helps organelles move throughout the cell

14. Power Plant Mitochondria
Produces energy for the city
Tiny bean shaped structure in cytoplasm
Highly folded inner membrane
Supplies energy for the cell by transforming sugar into energy
