1. CELL THEORY: 1. All living things are composed of cells.
2. Cells are the basic units of structure and function in living things.
3. All cells are produced from other cells.

2. What’s Inside an Animal Cell?

3. What are organelles? Tiny structures inside a cell.
They carry out specific jobs within the cell.
Kind of like organs for a cell.

4. CELL MEMBRANE The cell membrane is the outer doors of the cell.
FUNCTIONS:
It lets things in and out of the cell
It holds everything together.

5. CYTOPLASM
A jelly-like fluid that contains all of the organelles of the cell.
FUNCTIONS:
Holds all the organelles inside of the cell in a moving fluid.

CYTOPLASM

7. NUCLEUS
The “brains” or control center of the cell.

8. Nucleus
Rough ER

9. Nucleolus A small oval structure in the Nucleus that makes Ribosomes.
FUNCTIONS:
To make Ribosomes.

10. NUCLEUS = the whole peach
NUCLEOLUS = the pit

11. VACUOLES Large water-filled sacs floating in the Cytoplasm. FUNCTIONS:
Store food and other materials needed by the cell.

12. VACUOLE

13. MITOCHONDRIA Rod-shaped structures found in the Cytoplasm. FUNCTIONS:
They convert food energy into energy the other organelles use to do their job. “POWERHOUSE OF THE CELL”

14. MITOCHONDRIA

15. ENDOPLASMIC RETICULUM (ER)
A maze of passageways in the Cytoplasm.
TWO KINDS OF ER IN ANIMAL CELLS:
Rough ER – Have Ribosomes attached
Smooth ER – No Ribosomes attached
FUNCTIONS:
To carry proteins and other materials from one part of the cell to other parts.
Many of the cell’s chemical reactions occur here.

16. ENDOPLASMIC RETICULUM
ROUGH ER
SMOOTH ER

18. LYSOSOMES
Small round structures found in the Cytoplasm. They contain digestive enzymes.
FUNCTIONS:
They break down materials with their digestive enzymes.

19. LYSOSOMES
Chemicals

20. RIBOSOMES
Small grain-like bodies found on the Rough ER and floating around the Cytoplasm. They are like protein factories. There are more ribosomes in a cell that any other organelle.
FUNCTIONS:
They make Proteins

21. A Whole Ribosome

22. GOLGI COMPLEX Flattened sacs and tubes found in the Cytoplasm.
FUNCTIONS:
Receives proteins from other Smooth ER.
Packages the proteins up.
Sends them to other parts of the cell.

23. GOLGI COMPLEX

24. ORGANELLES IN AN ANIMAL CELL

25. EUKARYOTIC CELL – HAS A NUCLEUS
PROKARYOTIC CELL – DOES NOT HAVE A NUCLEUS
