Download Cell Parts compared to a city

Review question
You find a cell that has no nucleus and no cell
organelles. What kind of cell is this?
a. Plant cell
b. Animal cell
c. Prokaryote cell
d. Eukaryote cell
•Organelles – “little
organs” specialized for
specific functions
Cell Parts compared to a city
Cell Membrane
• Like a gatekeeper to the city
• Allows certain things to enter or exit the cell
• Keeps water from “drowning the cell”
Nucleus
• Like the Mayor
• Directs cell activity
• Contains the cell’s DNA
Cytoplasm
• Jelly-like substance that keeps everything in
their place
Mitochondria
• Like a powerplant it generates energy
• converts chemical energy stored in food into
compounds that are more convenient for the
cell to use
• breaks down
carbohydrates to
produce energy
Ribosome
• Like meat factories
• Produce protein for the cell
Endoplasmic Reticulum
• Like Restaurants
• internal membrane systems of folded sacs and
interconnected channels where Lipids, proteins,
and carbohydrates are made.
• Two types:
1. Smooth ER – modifies lipids
and detoxifies drugs
2. Rough ER- where proteins
are made, ribosomes are on
the surface
Golgi Apparatus
• Like UPS: Package and ship items
• modifies, sorts, and packages proteins and
other materials from the rough ER in vesicles
• Use Vesicles to ships things,
Vesicles are like the trucks
Lysosome
(small and filled with enzymes)
• Like the clean up crew
• Clean up the cell or break down materials by
digesting worn out organelles and food
particles
• help package and distribute proteins from the
Golgi
Vacuoles
• Like a food pantry
• Used to store food, enzymes and other
materials.
Cytoskeleton
• Like scaffolding
• Provides support and structure for the cell.
• Microfilaments – threadlike protein (actin)
– tough, flexible framework
– help cell to move
• Microtubules – hollow protein structures (tubulins)
– maintain cell shape
– cell division (mitotic spindle & centrioles)
– projections (cilia & flagella) for movement
Differences in a plant cell
• Plant cells have cell wall
• This is inflexible and provides support and
protection for the cell
Chloroplast
• Like a solar panel
• Takes light from the sun and converts it into
energy for the plant cell to use.
Vacuole
• In a plant cell they have one very large
vacuole, animal cells have a few small
vacuoles.

• A cell is found to have a rectangular shape.
What type of cell would this most likely be?
a. Plant cell
b. Animal cell
c. Fungi cell
d. Prokaryote cell

Title: Cell Analogies
• Create an analogy comparing parts of a cell to
a School or home (pick one)
• Remember an analogy is a comparison so
make sure to look at what each part of the cell
does. For example, look at the parts and roles
of a classroom, bedroom, closet, buses, etc.
