1. Monday Agenda Think back to the beginning of the year. What are the 8 characteristics of living things? How do they relate to cells? 1.Lab Overview 2.Week Outline 3.Organelle Lecture Hw: Study for Quiz

2. Agenda Monday: Organelle Lecture Tuesday: No Class Wednesday: Quiz Thursday: Finish organelles and Cell Activity Friday: Winter Break Cell-ebration (movie)

4. LE 4-3b Prokaryotic flagella Ribosomes Cell wall Plasma membrane Nucleoid region (DNA) Pili Prokaryotic cell DNA not bound by a membrane Cytoplasm

5. Prokaryotic Cell Basic cell type Does not contain membrane-bound organelles Bacteria and archaebacteria

6. Eukaryotic cell

7. Manufacturing Nucleus – makes DNA & RNA

8. Manufacturing Nucleus – makes DNA & RNA Ribosomes – make proteins

9. Manufacturing Nucleus – makes DNA & RNA Ribosomes – make proteins Rough ER – make membrane lipids & proteins

10. Manufacturing Nucleus – makes DNA & RNA Ribosomes – make proteins Rough ER – make membrane lipids & proteins Smooth ER – make lipids

11. Manufacturing Nucleus – makes DNA & RNA Ribosomes – make proteins Rough ER – make membrane lipids & proteins Smooth ER – make lipids Golgi Apparatus – stores, modifies & transports proteins; makes lysosomes

12. Analogies? Nucleus Ribosome Rough ER Smooth ER Golgi Apparatus

13. Stop and talk Which of the following organelles does not belong in the list: a.Nucleus b. Rough ER c. Ribosome d. Golgi Apparatus

14. Stop and talk Contrast the form and functions of smooth ER and rough ER

15. Breakdown Lysosomes (in animals, some protists)– digests ingested food & old organelles

16. Breakdown Lysosomes (in animals, some protists)– digests ingested food & old organelles Vacuoles– digestion, stores chemicals, maintains water balance

17. Analogies? Lysosome Vacuole Easier to see in plants

18. Stop and Talk How is a lysosome like a recycling center?

19. Support, Movement, & Communication Cytoskeleton Maintains cell shape Anchors organelles Moves organelles Moves cells Transmits cell signals (between cells)

20. Microtubule Intermediate filament Microfilament Cytoskeleton Support, Movement, & Communication

21. Cytoskeleton Cell wall -- Maintains cell shape Provides skeletal type support Surface protection

22. Plants Only Cell Wall Large Central Vacuole

23. Energy Mitochondria – convert chemical energy of food to chemical energy of the cell (ATP)

24. Analogies? Mitochondrion

25. Energy Mitochondria – convert chemical energy of food (sugar) into chemical energy of the cell (ATP) Chloroplast (only plants, some protists) – converts light energy into sugar

26. Analogies? Mitochondrion Chloroplast

27. LE 4-4a Rough endoplasmic reticulum Smooth endoplasmic reticulum Nucleus Flagellum Lycosome Centriole Peroxisome Microtubule Intermediate filament Microfilament Cytoskeleton Golgi apparatus Ribosomes Plasma membrane Mitochondrion Eukaryotic animal cell Not in most plant cells

28. Eukaryotic plant cell LE 4-4b Not in animal cells Golgi apparatus Nucleus Central vacuole Chloroplast Cell wall Mitochondrion Peroxisome Plasma membrane Rough endoplasmic reticulum Smooth endoplasmic reticulum Ribosomes Microtubule Intermediate filament Microfilament Cytoskeleton
