1. The Cell Objectives Explain how life is organized
Differentiate between a prokaryotic and eukaryotic cell
Describe the parts and functions of a eukaryotic cell

2. The Cell

3. Overview of the Cell I. Organization of Life Simple Complex
Each complex system relies on the simpler system

4. Organism Organs Tissues Organ systems
Organization in the human body from smallest to largest working systems
Atoms
Molecules
C e l l s
Tissues
Organs
Organ systems
Organism

5. * Atoms: smallest particle on earth; nonliving
* Molecules: a group of atoms
* Cells: smallest living thing
* Tissues: group of cells working together; epithelial, cardiac, nerve, smooth

6. *Organs: group of tissues
working together
*Organ Systems:
group of organs
* Organism: group of organ systems working together

7. Population – a group of the SAME kind of organism
Communities – two or more populations in a specific environment
Ecosystem – all of the living and nonliving things in a specific environment

9. II. Types of Cells A. Prokaryotic *Bacteria
*Circular DNA (like elastics)
*No nucleus
*No membrane covered organelles (only DNA, ribosome's, cytoplasm, cell wall & membrane)

10. B. Eukaryotic *nucleus *Membrane covered organelles
*Linear DNA (like bowties)
All other cells: Plant, animal, fungi, protists

Large Vacuole * only plant cell
Cell Wall * only plant cell
Chloroplast * only plant cell

12. III. Functions
Nucleus- Control center
“brain”

13. Cell Membrane-“door” “border patrol” Regulates what enters and exits the cell…Outer layer of the cell.

14. Mitochondria- Powerhouse of the cell: produces ATP “mighty mouse”

15. Golgi Complex-“FedEx” transport proteins/other materials out of the cell

16. Lysosome- “lysol” waste products (old organelles, foreign invaders, wastes). Acts like the cleanup crew.

17. Ribosome- “ribs-meat-protein” amino acids hook together to form proteins.

18. Endoplasmic Reticulum- “ER” Makes lipids, packages and releases proteins for the cell. Roadways of the cell.

19. Vacuole- “water hole” Stores water (large in plants).

20. Cytoplasm- “jellylike” Fluid that holds all organelles in place

21. DNA- “blueprints of life” Special molecule found inside nucleus

22. Organelles only in plants
Cell Wall- Gives a plant support. Chloroplast- Traps sunlight and converts it into food. Chlorophyll- made and stored here…makes plants green

23. Cells can perform many functions B. Unicellular One cell
IV. Types of Organisms
A. Multi-cellular
Composed of many cells
Cells can perform many functions
B. Unicellular
One cell
One cell can’t do many functions

24. V. Cell Theory
A. History
Robert Hooke- discovered cells while looking at a cork.
Anton Van Leeuwenhook- made discoveries
Schleiden, Schwann, Virchow created the cell theory.

25. Parts of the cell theory
All organisms are composed of one or more cells.
The cell is the basic unit of life.
All cells come from pre-existing cells. `

27. Microscope Animal Cell vs. Plant Cell
