1. Chapter 7 The Cell Basic unit of life. Come from pre-existing cells.
Organelles-Act like little organs of a cell
Shape tells function
2 Types of Cells

2. Prokaryotic Cells Smaller No nucleus No membrane-bound organelles
Bacteria
Blue-Green Algae
Archaea
Binary Fission

3. Prokaryotes
Streptococcus pyogenes, Anabaena, and Methanogens

4. Eukaryotic Cells Larger Nucleus Membrane-bound organelles
All other life: (Animals, Plants, Fungi, Protists)

5. Eukaryotes
Cougars, Eastern Red Cedar, Bread Mold, and Amoeba proteus

6. Organelles Common to All Cells
Plasma Membrane-Boundary between cell and environment.
Homeostasis
Semi-Permeable
Phospholipids
Bilayer

7. Cytoplasm
All material inside cells
Holds organelles
Mostly water

8. Ribosomes
Protein Synthesis

9. Other Organelles
Nucleus-Brain of cell/controls all cell activities. Cell division.
Chromatin-DNA spread out in nucleus
Nucleolus-Dark spot. Makes ribosomes.

10. Plasmids
Circular DNA
Prokaryotes

11. Mitochondria Cellular Respiration (plants and animals)
“Powerhouse” of cell
Uses oxygen to turn food (glucose) into energy
Has DNA

12. Chloroplast Photosynthesis Contains chlorophyll Has DNA
Only Plant Cells

13. Vacuole
Storage
Giant water bubble
Plant cells
Contractile Vacuole

14. Contractile Vacuole
Water balance ( some animal cells ex.
Paramecium)

15. Eyespot
Sensitive to light (Euglena)

16. Movement
Flagella
Cilia

17. Pseudopods
Extension of cytoplasm (Amoeba)

18. Cell Wall Thick, rigid border around cell membrane.
Plant Cells, fungi and Prokaryotes only
Maintains shape/structure
Plants-Cellulose
Fungi-Chitin

19. Adaptive Behavior Chemotaxis-Attraction to chemicals
Phototaxis-Attraction to light
