1. Parts and Functions of Eukaryotic Cells Chapter 7

2. Animal Cell
Plant Cell

3. Nucleus
Contains the genetic material and controls the cell’s activities.
Provides protection for nuclear material
Composed of three parts: nuclear envelope, nucleolus, chromatin
Plant, Animal cell

4. Nuclear Envelope
Double –membrane layer that surrounds the nucleus of a cell

5. Nucleolus Small, dense region within most nuclei
produces rRNA-used to make ribosomes
Plant, Animal cell

6. Ribosome Site of protein synthesis (where proteins are made)
May be either free-floating or attached to E.R.
Plant, animal cell

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

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

9. Lysosome
Contains digestive enzymes needed to break down cellular debris/ “junk”, Cleanup crew
Plant, animal cell

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

11. Cytoplasm Area between the cell membrane and the nucleus.
The gel-like substance in the cytoplasm is called cytosol
Plant, animal cell

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

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

14. The following are found in ANIMAL cells ONLY

15. Cilia Flagella A form of microtubule
Short, hair-like projections that allow cells to move
Animals cell
Flagella
A form of microtubule
Long, hair-like projections that allow cells to move
Animals cell

16. Centriole It helps organize microtubules during cell division
Helps build cilia & flagella
Animal cell ONLY

17. The following are found in PLANT cells ONLY

18. Cell Wall
Tough, rigid outer covering that provides structure and protection.
Plants, algae, and some bacteria
Made of:
Cellulose – Plants
Chitin – Fungi
Peptidoglycan - Bacteria

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

20. Leukoplast
Stores starch, lipids, proteins
Plants cells

21. Vacuole Membrane-bound sac, largest structure in plant cell
Helps maintain water pressure in the cell
Site in the cell where water, salts, proteins, and carbohydrates are stored
Plants, some animals
