1. A Cell is like a Factory

2. How can a cell be like a factory???
•In a factory, you have many different tasks
being completed in the same building.
–Ex. The building supports/shelters the
workers, workers build goods, maintenance
crews clean up messes, shipping department
gets goods ready to leave the factory and so
on….
•A cell can be thought of as a "factory," with
different departments each performing
specialized tasks.

3. The Cell wall is like a…..
• a security Gate
–A security gate protects the factory and helps
keep it safe.
–A cell wall does the same thing for a plant
cell!

4. The cell membrane is like…
•Front doors
–The doors of a factory regulates what enters
and leaves the building
–A cell membrane does the same thing for
plant and animal cells!

5. The Nucleus is like…..
•THE BIG BOSS!! (CEO) The boss
controls all of the activity inside the cell
•The nucleus does the same thing for plant
and animal cells

6. Cytoplasm is like……….
•The factory floor. The floor of the factory
has all the workers, machines, equipment
on it
•Cytoplasm holds all of the organelles (cell
parts) in the plant and animal cells

7. Endoplasmic Reticulum (ER) is
like…….
•An assembly line….(where the workers do
their work) Items move along a conveyer
belt to different parts of the plant
•ER moves items to different parts of the
cell in the same way!

8. Ribosomes are like….
•Workers on the assembly line…they are
responsible for building the goods in a
factory
•Ribosomes assemble (build) proteins

9. Vacuoles are like…..
•Break rooms- In a break room you have
storage for food items and places to get rid
of trash
•Vacuoles hold wastes and stores water in
plant and animal cells.
–Which cell has 1 large vacuole?

10. Lysosomes are like…..
•Maintenance/janitor crews……in a factory
these guys break down, clean up, and
repair items in and around the factory
•Lysosmes do the same thing in the cell

11. Mitochondria and Chloroplasts are
like…..
•Power Stations……the power station
supplies energy to the factory
•Mitochondria (animal cells) and
Chloroplasts (plant cells) do this for a cell!
