Virchow

3. Section 8.1 CELL THEORY All living things are composed of cells
Cells are the basic units of structure and function in living things
New cells are produced from existing cells

4. Section 8.1
Microscopes
Light
Electron
SEM
TEM

5. Section 8.1 PROKARYOTES EUKARYOTES NO nucleus
NO membrane-bound organelles
Small and simple
Ex. Bacteria
Nucleus
Membrane-bound organelles
Larger and more complex
Ex. Plants, animals, fungi, protists

6. Section 8.2 ANIMAL CELLS PLANT CELLS Centrioles
help organize cell division
**Animal cells do have small vacuoles
**Some have contractile vacuoles
Cell wall
Protection and support; water pressure
Chloroplasts
Photosynthesis
Large central vacuole
Water storage

7. Section 8.2
ORGANELLES
Structure and function (what they look like and what they do)
Study your organelle chart
Remember to look at your extra notes for Section 8.2 (microfilaments, microtubules, etc.)

8. Section 8.2 Chromatin- granular material made of DNA and protein
Chromosomes- threadlike form of DNA seen only during cell division

9. Section 8.3 Structure and Function
Cell membrane (make sure you know all components of the cell membrane…carbs, proteins, etc.)
Cell wall
Concentration = mass solute/volume solution
Equilibrium

10. Section 8.3 PASSIVE TRANSPORT Diffusion Osmosis Facilitated diffusion
High  Low
Does NOT use energy
Happens because molecules are always in motion
Diffusion
Osmosis
Facilitated diffusion

DOES use energy
Use a protein pump
Endocytosis
Phagocytosis
Pinocytosis
Exocytosis

13. Section 8.4 Unicellular vs. multicellular Cell specialization
Cells  tissues  organs  organ systems
