1. The Animal Cell Key Concept: Eukaryotic cells contain membrane bound organelles
All living things are composed of cells
Eukaryotic cells contain membrane-bound organelles

2. Cell Membrane/Plasma Membrane
Barrier to extra-cellular environment
Allows nutrients in and wastes out
Identifies the cell
Receives messages from other cells

3. Nucleus Controls the cells activities
Contains the genetic material (DNA)
Surrounded by a nuclear membrane

4. Nucleolus
Manufactures ribosomes

5. Nuclear Membrane Keeps the DNA inside
Allows the RNA to pass into the cell

6. Cytoplasm Gel-like fluid that fills the cell
Breaks down some glucose for energy (glycolysis) – not much energy
Filled with free-floating subunits

7. Mitochondria
Metabolizes glucose for energy – provides a great deal of energy
Has its’ own DNA
Has a double membrane

8. Endoplasmic Reticulum
Two types of ER
RER (rough endoplasmic reticulum) contains ribosomes
Manufactures and transports proteins
SER (smooth endoplasmic reticulum) has no ribosomes
Manufactures and transports lipids

9. Ribosome Makes proteins Sometimes attached to RER
Sometimes free-floating in the cytoplasm

10. Golgi Apparatus Packages proteins Modifies proteins
Prepares them for export to the organism outside the cell

11. Vesicle
Transports proteins to and from the Golgi apparatus

12. Lysosome Digests worn out organelles
Destroys infected or un-necessary cells
Contains digestive enzymes

13. Centriole The centriole is found only in animal cells
It is involved in cell division

14. Plant Cells
Plant cells have many of the same organelles as animals cells

15. Plant Cells Have 2 Extra Organelles
Outside the cell membrane, plants have a cell wall
Plants have large central vacuoles
Plants have chloroplasts to convert sunlight to glucose

16. Chloroplasts Use CO2, H2O and sunlight to produce Carbohydrates
Releases O2
Contains double membrane
Has its’ own DNA

17. Chloroplast Chlorophyll does the work
Chlorophyll is located in the thylakoid stacks
Thylakoid stacks are called granum

18. Shape and Support
Made of cellulose (an indigestible form of carbohydrate)
Found just outside the plasma membrane

19. Transport Into & Out of the Cell
Materials move from areas of high concentration to areas of low concentration
This is called diffusion
