1. Cell Theory Galileo First observations made with a microscope
Robert Hooke
Made simple microscope
Looked at cork
observed small box like structures
Called them cellulae (small rooms) = cells

2. Cell Theory Anton van Leewenhoek Created a microscope
Saw living things in milk, pond water, etc
Matthias Schlieden
Looked at plants and concluded they were composed of cells

3. Cell Theory Theodore Schwann Animals composed of cells Rudolph Virchow
All cells are produced from the division of existing cells

4. Cell Theory All living things are composed of one or more cells
Cells are the basic unit of structure and organization of all living organisms
Cells arise only from previously existing cells
Cells pass on copies of their genetic material to their daughter cells

5. Prokaryotic vs. Eukaryotic
** Organelles – specialized structures in cells that carryout specific functions
Prokaryotic Cells
Prokaryotes
Small and simple
No nucleus or membrane bound organelles
Usually unicellular
Bacteria
Eukaryotic Cells
Eukaryotes
Higher level organisms and function
Most organisms are made up of eukaryotic cells
Nucleus –organelle that contains DNA
Other membrane bound organelles

6. What are all living things composed of?
Agenda for Tuesday Nov. 2nd
Cell theory
Prokaryotic and Eukaryotic cells
Cell structure

7. List the 3 parts of Cell Theory
Agenda for Thursday Feb 10th
Organelle Notes
Cell City Analogy
Cell Coloring

8. Organelles in the Cell Plasma membrane Cell Wall – plants and fungi
Controls what enters and leaves cell
Both prokaryotic and eukaryotic cells
Cell Wall – plants and fungi
support and protect the cell
Plants’ cell walls composed of cellulose
fungi have walls composed of chitin

9. Organelles in the Cell Nucleus - contains DNA
DNA – instructions needed to produce proteins that control  metabolism and other cell functions
Cytoplasm - material enclosed by the plasma membrane
Liquid within the cell

10. Organelles Nucleolus – within nucleus Nucleoplasma
Ribosomal RNA (rRNA) is created here
Nucleoplasma

11. Organelles – ER Single, continuous membrane
Pipes, tubes and tunnels in cell
Continuous with nuclear envelope
Superhighway of the cell
2 kinds: Rough ER + Smooth ER
Rough ER - Studded, or covered, with ribosomes
Major site of protein synthesis

12. Golgi Apparatus Handles export and import of material for cell
Functions:
Storage, packaging, sorting and final touches and modification of proteins before exportation
The UPS of the cell

13. Vesicles and Vacuoles Transport Vesicles
Transport material from ER to Golgi
Transport of finished product from Golgi to Cell Membrane for export (reversed for import)
Lysosomes &Peroxisomes
Contain digestive enzymes
Breakdown cell's food and wastes
Detox alcohols and hydrogen peroxide

14. Mitochondria Produces energy for the cell Composed of 2 membranes
Cell's "power house"
Composed of 2 membranes
Cristae = folds of inner membrane, site of energy production
Matrix = fluid inside mitochondria

15. Chloroplasts Found only in green plant cells and algae
Site of photosynthesis
Contain the pigment chlorophyll
Thylkaloid – single disk, site of photosynthesis
Grana = stacks of thylkaloid
Stroma = fluid inside chloroplast

17. Cytoskeleton Framework of protein fibers inside cell
Support and movement (dynamic)
Composed of:
Microfilaments = thinnest (actin)
Intermediate filaments = (composition varies)
Microtubules = thickest (tubulin)

20. What are some differences between prokaryotic and eukaryotic cells?
Agenda for Friday Feb 11th

Finish Coloring
Cell City Analogy

21. Prokaryotic vs. Eukaryotic
Prokaryotic Cells
Prokaryotes
Small and simple
No nucleus or membrane bound organelles
Usually unicellular
Bacteria
Eukaryotic Cells
Eukaryotes
Higher level organisms and function
Most organisms are made up of eukaryotic cells
Nucleus –organelle that contains DNA
Membrane bound organelles

22. Plant vs. Animal Cell Plant Cells Cell Wall Chloroplasts
And cell membrane
Chloroplasts
Large vacuoles
Animal Cells
No Cell wall
Cell membrane only
No Chloroplast
Small or absent vacuoles
All other organelles are the same in each cell
