knowledge
City Limits
Cell Membrane
• Controls what
goes in and out
of a city
• A thin flexible
covering that
surrounds the
cell
• Controls what
goes in and out
of the cell
Return to City
Return to cell
Road System
• Allows for
movement
throughout the
city
Return to City
Endoplasmic Reticulum
• A network of
tube-like
passageways
through which
proteins from
the ribosomes
are transported
Return to cell
City Hall
•Controls all the
activities of the
city
Return to City
Nucleus
•A large,
round/oval
structure near
the center of
the cell that
controls all of
the activities in
the cell
Return to cell
City Auditor
•Stores all the
records of the
city and passes
them on as the
city grows
Chromosomes
•Rod-shaped
bodies found in
the nucleus that
pass on
hereditary traits
Return to City
Return to cell
City Planning
•Place in city hall
where plans are
made for the
construction of
the city
Return to City
Ribosomes
•Grain-like
bodies made of
RNA in the
nucleolus where
proteins are
produced
Return to cell
Food Processing
Plant
Lysosomes
•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 City
Return to cell
Warehouse
•Stores
materials needed
by the city
Return to City
Vacuole
•A large round
sac in the
cytoplasm
•Stores water,
food, wastes
Return to cell
Construction
Company
•Builds structures
for the city
Return to city
Nucleolus
•Small dense
object found in
the middle of
the nucleus
•Makes RNA for
the cell
Return to cell
Delivery Van
Delivers products
made at the
construction
company to other
locations in the
city
Return to city
Cytoplasm
Jelly-like;
Helps organelles
move throughout
the cell
Return to cell
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
