Reflect: (3 Minutes)

1. Reflect: (3 Minutes) What is a “cell”? Where do you find “cells”? What are two cells you encounter everyday?

2. Organelles – Parts of a Cell • Many different organelles in eukaryotic cells. • Each has different structure and function.

3. Analogies (Just like …) There are lots of different parts of cells (organelles) They Work Just Like the parts of big factories, office building or even schools.

4. Plasma Membrane

5. Like the exterior of a school, the plasma membrane controls what enters and leaves a cell. Exterior of School Plasma Membrane Plasma Membrane

6. Nucleus

7. Like a principal, the nucleus controls what the cell does and what it produces. Nucleus Principal

8. Mitochondria

9. Like a lunch room, the mitochondria provide energy for the cell to function. Mitochondria Lunch Room

10. Endoplasmic Reticulum

11. Like a copy room, the ER is the place where the product (proteins) of the cell are made ER Copy Room

12. Like printers, the ribosomes make the products (proteins) of the cell Ribosomes Printers

13. Golgi Apparatus

14. Like the mail room, the golgi apparatus packages materials for transport out of the cell Golgi Apparatus Mail Room

15. Lysosome

16. Like garbage disposal, the lysosomes get rid of waste materials in the cell Lysosomes Garbage Disposal

17. Cytoskeleton

18. Like school walls, the cytoskeleton helps maintain shape and anchor organelles in place Cytoskeleton Walls

19. Animal Cell

20. Projectiles Allows animal cells to move in watery environments and capture food long, few-1 to 3, found at the ends of cell short, numerous, surrounds the entire cell

21. Centriole Bundle of tubes, which line up the DNA and separates it during animal cell division

22. Plant Cell

23. Chloroplast Stores energy for later; contain green pigment; captures light energy (sunlight) and converts it to chemical energy (glucose)

24. Central Vacuole • Stores water, maintains fluid balance, keep pressure on cell wall to keep it rigid

25. Cell Wall Surrounds plants cells; provides structural support and protection

26. Create your own analogy for the following organelles. Projectiles Centrioles Cell Wall Chloroplast Central Vacuole

27. Exit Slip Share out one of your analogies.

28. 1. Function for Mitochondria 2. Analogy for Mitochondria Bell Ringer 3. Function for Nucleus 4. Analogy for Nucleus

29. Word Association Match each organelle with the analogous term: Plasma membrane Proteins Vacuoles Lysosomes Ribosomes Boxes Factories Gate Trash Compactor Merchandise

30. Guided Reading Read each section of the article “When Cells Face an Energy Crisis” about the disorders caused by mitochondria malfunctioning. As you read, answer the corresponding questions to help you summarize some of the significant points in the article .

31. Think It Out Breakthroughs in medicine and technology arise from people thinking innovatively about concepts that have been about for a very long time, such as the research on rare mitochondrial disorders, you just read about.

32. Think It Up Select an organelle, NOT mitochondria, and write out its function. Think about what would happen to the cells and the organism made up of these cells if this organelle malfunctioned. Write 75-100 words to describe the malfunction (What is this organelle not doing or doing to much of? What should it be doing?). Predict how this will affect the cells and the organism (Will it die? Will it not be able to reproduce? How and why?). Be creative and detailed in your description.
