2. Questions of the Day Eukaryotic or Prokaryotic?

3. Prokaryotic or Eukaryotic?

5. Prokaryote or Eukaryote?

6. Goals for the Day 1. Learn the basic functions of Eukaryotic cell organelles 2. Be able to separate organelles as belonging to plant cells, animal cells, or both. 3. Be able to separate organelles as belonging to Prokaryotes or Eukaryotes

7. Question What cell organelles (parts of a cell) have you heard of before? List as many as you can think of.

8. Cell Organelles Organelles – Organs for cells Nucleus Controls all cell activities Contains DNA

9. Eukaryotic Cells Eukaryotic cells have: A nucleus which contains the cell’s DNA Other internal compartments called organelles.

10. Nucleus of a Cell

11. The Nucleus, continued

12. Ribosomes and the Endoplasmic Reticulum Endoplasmic Reticulum (ER) Transportation Two kinds: Rough and Smooth Rough has ribosomes- makes/transports proteins Smooth makes/transports lipids

13. Endoplasmic Reticulum The ER moves proteins and other substances within eukaryotic cells.

14. Golgi bodies Storage and Packaging The UPS of the cell Golgi bodies

15. Lysosome Lysosomes- small, spherical organelles that contain the cell’s digestive enzymes Function: Digestion & Recycling (The garbage man of the cell)

16. Structures of Plant Cells Plants have three unique structures that are not found in animal cells: Cell Wall Chloroplasts Central Vacuole

17. Structures of Plant Cells Cell Wall –surrounds the cell membrane of plant cells, and is made of proteins and carbohydrates. Functions of the Cell Wall: helps support and maintain the shape of the cell protects the cell from damage connects the cell with adjacent cells

18. Structures of Plant Cells Chloroplasts convert light energy into USABLE energy

19. Mitochondria (Powerhouse of the cell) Convert sugar into usable energy (ATP) Where in your body would you need a lot of mitochondria? Mitochondria

20. Mitochondria, continued Mitochondria have an inner and an outer membrane.

21. Mitochondria & Chloroplasts Unique features of the mitochondria & chloroplast: Both are energy-related organelles Have two membranes Have their own DNA Reproduce separately from the cell

22. Structures of Plant Cells Central Vacuole: Takes over the function of the Lysosome, which is not found in plant cells!!! Why might plants want to retain toxins and wastes inside the cell???

23. Comparing Plant and Animal Cells

24. Organelle Billboard Imagine you are in charge of marketing for a particular cell organelle. You will make a billboard that represents the shape of your organelle. On the back side of the organelle you will need to come up with a marketing slogan that represents the function of the organelle, and finally a simile about what your cell organelle is like, this should also have something to do with its function.

25. Organelle Marketing Once you have completed your organelle, slogan, and simile, determine what organism groups your organelle would be found in. prokaryotes, eukaryotes, both Plants, animals, both You will need to include this information in your presentation You may earn extra points by developing a slogan and simile for the cell membrane and cell wall

26. 1. Nucleus 2. Cell Wall 3. Cell Membrane 4. Endoplasmic reticulum 5. Central Vacuole 6. Chloroplast 7. Golgi Bodies 8. Ribosomes 9. Mitochondria 10. Marker Proteins 11. Channel/Transport Proteins 12. Receptor Proteins Extra Credit: Lysosome
