1. Cell Parts Worksheet Parts of a Cell:
cell support structures, nucleus, cytoplasm, lysosomes, golgi apparatus, ribosomes, endoplasmic reticulum, mitochondria, chloroplast, vacuole

2. 1. Cell support structures
Cytoskeleton
Support structure
Maintain the shape of a cell

3. 1. Cell support structures
Cell Membrane
Made of lipids and proteins.
Lipid bi-layer: “2-layers” of fat
Allows materials to enter and exit the cell
Semi-permeable: only some things go through
Found in plant AND animal cells
Also called the plasma membrane

4. 1. Cell support structures
Cell Wall
Protects and supports the plant.
Found only in plant cells

5. 2. nucleus Control center of the cell Contains DNA Nucleolus
Nuclear Membrane

6. 3. NUCLEOLUS
Produces ribosomes

7. 4. cytoplasm Portion of the cell outside the nucleus
Works with the nucleus

8. 5. lysosomes
Digest lipids, carbohydrates, and proteins into smaller parts
Breakdown old organelles

9. 6. Golgi Apparatus
Packages and modifies the protein made by rough E.R.
Can also package hormones, enzymes, and mucus

10. 7. ribosomes Makes (synthesizes) proteins
May be free- floating or attached to the E.R.

11. 8. RER: rough endoplasmic reticulum
Has ribosomes on it.
Makes (synthesizes) proteins.
Some proteins go to the cell membrane, others are released by the cell.

12. 8. SER: smooth endoplasmic reticulum
Without ribosomes
Makes (synthesizes) lipids used by the cell membrane.

13. 9. mitochondria
Converts glucose into ATP.
“Food” into “energy”

14. 10. chloroplast Where photosynthesis takes place.
6CO2 + 6H2O C6H12O6 + 6O2

15. 11. vacuole Found in plants Storage center
Stores materials like water, salts, proteins, and carbohydrates
