1. Cells: The Basic Units of Life
1.2

2. Organelle= “little organ”
All the stuff in between the organelles is cytoplasm

4. “Cell Boundary”
separates the inside of the cell from the external environment
controls the flow of materials into and out of the cell

6. “The Brain” Controls all cell activities
Holds the DNA (genetic material)

8. “Roads”
Made up of channels that transport material made in the cell from one place to another
Rough ER & Smooth ER

9. Rough ER= filled with RIBOSOMES; it makes proteins
Smooth ER = NO RIBOSOMES; it makes lipids

11. “Protein Factory”
Make proteins

13. “Shippers”
Sorts products from the ER (proteins and lipids) and packages them into vesicles

15. “Clean Up Crew”
Contain proteins (enzymes) that break down food into smaller particles
Destroy old cells, recycle the parts
Destroy invaders
Garbage disposal
Only found in animal
cells

17. “Powerhouse” Makes energy for the cell Contains a double membrane
Has it’s own DNA

19. “Storage”
Sacs that fill with food being digested and waste material that is on its way out of the cell
Water is also stored here
Plant cells- central vacuole

21. “Spiderman” Protein tubes that play a role in cell division
Usually only in animal cells
Shoot out spindle fibers that guide chromosomes during cell division

23. photosynthesis

24. Flagellum Long, tail-like projection that extends from the cell
Used for locomotion

25. Cilia
Short, thin projections from cell
Help with locomotion

26. CRASH COURSE!
