1. Parts and Functions of Eukaryotic Cells Chapter 7

2. Animal Cell
Plant Cell

3. Nucleus Contains DNA Controls the cell’s activities.
Composed of three parts: nuclear envelope, nucleolus, chromatin
Plant, Animal cell

4. Nucleolus
produces rRNA-used to make ribosomes
Plant, Animal cell

5. Ribosome Site of protein synthesis (where proteins are made)
Plant, animal cell

6. Endoplasmic Reticulum (E.R.)
Network of membrane transport channels
Smooth ER (SER)
- Synthesis of lipids and steroids
- Detoxifies cell
Rough ER (RER)
- Synthesis and processing of proteins to be exported
Plant, animal cell

7. Golgi Apparatus
Packages proteins, lipids, enzymes from the ER for storage or secretion.
Sends stuff out of the cell in vesicles.
Plant, Animal cell

8. Lysosome Breaks down cellular waste, cleans up “junk” in the cell.
Plant, animal cell

9. Mitochondrion
Generates energy (ATP) from glucose
Plant, animal cell

10. Cytoplasm The gel-like, liquid substance in the cell (cytosol)
Plant, animal cell

11. Cell Membrane
Thin, flexible barrier around a cell that regulates what enters and leaves the cell.
Plant, animal cell

12. Cytoskeleton Microfilament Microtubule Plant, animal cell
Cell membrane
Endoplasmic
reticulum
Microtubule
Microfilament
Ribosomes
Mitochondrion
Long, thin filament that helps in the movement and support of the cell
Hollow tube of protein that maintains cell shape and functions as a “train track” along which organelles move through the cell
Plant, animal cell
Microtubule

13. The following are found in ANIMAL cells ONLY

14. Cilia Flagella Short, hair-like structures that allow cells to move
Animals cell
Flagella
Long, hair-like structures that allow cells to move
Animals cell

15. Centriole It helps organize microtubules during cell division
Animal cell ONLY

16. The following are found in PLANT cells ONLY

17. Cell Wall
Tough, rigid outer covering that provides structure and protection.
Plants, algae, and some bacteria

18. Chloroplast Enables plants to make sugars through photosynthesis
Plants only

19. Leukoplast
Stores starch, lipids, proteins
Plants cells

20. Vacuole A sac that stores water, salts, proteins, and carbohydrates
Largest structure in plant cell
Plants, some animals (smaller)
