1. CELLS

2. Parts of the Cell

3. Organelle:
STRUCTURES inside the cell; “little organs”

4. Cytoplasm: Gel-like material inside cells

5. Cell Membrane: “GATE KEEPER”—Controls what goes in and out

6. NUCLEUS: Directs all cell activities
With the electron micro-scope

7. NUCLEOLUS: Helps to make protein;
Found inside nucleus

8. Found in nucleus; Contains genes or instructions for cell’s activities
CHROMATIN (aka: DNA):
Found in nucleus; Contains genes or instructions for cell’s activities

9. ENDOPLASMIC RETICULUM:
Pathway for moving materials through cell (the “express-way”); usually close to the nucleus

10. RIBOSOMES: Make protein. Some are stuck on the E. R
RIBOSOMES: Make protein! Some are stuck on the E.R. Some are in the cytoplasm.

11. MITOCHONDRIA: Releases energy in the cell; the “powerhouse”

12. CHLOROPLAST: Found in plants ONLY! Converts sunlight into cell energy
Under the microscope

13. CELL WALL: Found in plants only!
Outer structure; made of cellulose. Provides support.

14. VACUOLES: Store water, food, and waste products
VACUOLES: Store water, food, and waste products. Usually larger in plants!

15. GOLGI BODIES: Nicknamed “UPS”—Packages & secretes (ships out) substances made inside the cell

16. LYSOSOMES: Digests cell wastes and food “garbage disposal”

17. What are the two parts plant cells have that animal cells do not have?
Cell Walls
Chloroplasts

18. Prokaryotic vs. Eukaryotic
Prokaryotic Cells: NO NUCLEUS
Example: Bacteria
Eukaryotic Cells: have a TRUE NUCLEUS
Example: all cells in your body
