2. WARM-UP 10/23:
What are the 2 main types of cells? Which Domains do they consist of?
List 3 ways that eukaryotes differ from prokaryotes.

3. Science Starter 10/13
If you were absent yesterday, please hand in your Test Corrections!
Please fill in the blanks in the hierarchy of life:
Atoms  ___________  ___________  tissues

4. Science Starter 10/14: **Reminder! Extra credit due Friday!!
Compare and contrast Animal vs. Plant Cells
Animal Cell
Plant Cell

5. Notes 3- Eukaryotic Cells (Organelles!)5

6. Remember...
Eukaryotic cells are complex and have structures inside of them called organelles
Organelles are like organs for cells! 6

7. Cell Membrane Function: barrier between cell and environment
Gets things in and out of cell
Made up of lipids 7

8. Cytoplasm
Jello-like substance that holds all organelles in the cell 8

9. Nucleus Function: control center of cell Contains DNA
Surrounded by membrane (nuclear envelope) 9

10. Endoplasmic Reticulum
Network of membranes surrounding nucleus
Types:
Rough ER: ribosomes on surface
Function: package proteins for secretion
Smooth ER: no ribosomes on surface
Function: make lipids, detox drugs & poisons 10

11. Ribosomes
Function: construct proteins for cell or for export to other cells 11

12. Golgi Apparatus
Function: creating & packaging of materials (small molecules) for transport
Series of flattened membrane folds 12

13. Lysosomes
Function: cell digestion; recycle cell’s materials; programmed cell death 13

14. Vacuoles
Function: storage of materials (food, water, minerals, pigments)
Plants and animals have many small vacuoles
Plants only: large central vacuole -- stores water, ions 14

15. Mitochondria
Function: creates energy for the cell 15

16. Chloroplasts- PLANTS ONLY!
Function: site of photosynthesis
Contains chlorophylls (pigments) for capturing sunlight energy 16

17. Cilia and Flagella- Animal cells only!
Flagella: long and few; propel through water
Cilia: short and numerous; move/capture fluids 17

18. Cell Wall- Plant cells only!
Cell wall: protect plant, maintain shape
Composed of cellulose
Outside of cell membrane 18

19. Plant Cells Only Animals Cells Only
Central vacuole
Flagella
Chloroplasts
Cilia
Cell wall of cellulose 19

20. Typical Animal Cell:

21. CELL VIDEO 8 21

22. Parts of plant & animal cell p 108-10922

23. 23

24. 10/24
1. Name 3 organelles or cell structures and their function. 24

25. ENDOSYMBIONT THEORY Mitochondria & chloroplasts share similar origin
Prokaryotic cells engulfed by ancestors of eukaryotic cells
Evidence:
Double-membrane structure
Have own ribosomes & DNA
Reproduce independently within cell

26. Do Now 10/24
Name 5 organelles or cell structures and their function.
