6. As you can see plant and animal cells have many parts
As you can see plant and animal cells have many parts. We will focus on the animal cell and the 7 main organelles in this unit and their function.

7. What are organelles (cell parts) and their functions?

8. cell membrane
The cell membrane holds and protects the cell. It controls what substances come into and out of the cell.
“Gate of the Cell”

9. cytoplasm

The mitochondria produces most of the energy for the cell.
“Powerhouse of the Cell”

13. vacuoles The vacuoles store food, water, and chemicals.
“Storage Tanks”

15. nucleus
The nucleus regulates and controls cell activities, acting like the “brain” of the cell.
“Control Center”

17. chromosomes
The chromosomes direct the activities of cells. Thread like structures made of DNA. Found in the Nucleus
