1. PLANT AND ANIMAL CELLS Chapter 7

2. What’s a cell?  The structural, functional and biological unit of all organisms.  http://www.youtube.com/watch?v=m bcWGU8fpxA&feature=related http://www.youtube.com/watch?v=m bcWGU8fpxA&feature=related

3. Cell Membrane  The outer layer of the cell. Acts as a semi- permeable boundary between inside and outside allowing only certain things to pass through.

4. Cell Wall  ONLY IN PLANT CELLS  Provides structure and protection

5. Cilia & Flagellum  Provides movement for cells.  Cilia- Small, many  Flagellum- Large, few

6. Cytoskeleton  Provides structure to cell and acts as pathways for organelle movement

7. Cytoplasm  Thick, jelly-like fluid inside the cell that protects and supports organelles

8. Golgi Body  Modifies, transports and exports proteins

9. Vacuole  Fluid filled organelle that stores food, water and toxins in cells  Largest plant cell organelle

10. Lysosome  Mostly found in animal cells  Digests large molecules and old cell parts into smaller ones

11. Mitochondria  Breaks down sugars to release energy through respiration

12. Chloroplasts  ONLY IN PLANT CELLS  Uses photosynthesis to convert light, H2O and CO2 into glucose (energy)

13. Endoplasmic Reticulum  Carries material through cell  Aids in making proteins

14. Ribosome  Produces proteins for the cell, located either on ER or freely floating.  Thousands in cell, makes up around 25% cell mass.

15. Nucleus  Controls all cell activity and contains hereditary information (DNA)

16. Nuclear Envelope  Controls the movement of all materials in and out of the nucleus

17. Nucleolus  Produces ribosomes. A single nucleus may have more than one.
