WARM UP: Tuesday, Sept 18

1. WARM UP: Tuesday, Sept 18 • Reminder: write the warm up in your 3 brad folder • List 3 similarities between prokaryotic & eukaryotic cells

2. Cells: Organelles

3. Objectives • Define the term organelle. • List organelles found in living cells • Identify the important roles organelles play within a cell. • Compare and contrast animal and plant cells. • Label organelles in plant and animal cells.

4. Organelles • = organized or specialized structures within a living cell • = differentiated structure within a cell • = parts of the cell that act like specialized “organs”

5. 1.Cytoplasm • Description: fluid like substance that fills the area of the cell outside the nucleus • Function: site of many cellular activities; surrounds organelles

6. 2.Nucleus • Description: large organelle near the center of the cell, composed on DNA & proteins

7. 2.Nucleus • Function: control center of the cell (acts like a brain) • Chromatin = coiled up DNA in nucleus • Nuclear Envelope = surrounds nucleus • Nucleolus = makes ribosomes

8. nucleus cytoplasm nucleolus

9. 3.Ribosomes • Description: Small particles composed of RNA & proteins. Found either: • Free in the cytoplasm • Attached to other organelles • Function: make proteins

10. ribosomes nucleus cytoplasm nucleolus

11. 4.Endoplasmic Reticulum (ER) • Description: network of membranes within the cytoplasm • 2 Types: • Smooth ER • Round ER

12. 4.Endoplasmic Reticulum (ER) • Function: • Smooth ER = makes lipids & detoxifies • Rough ER = sorts proteins & makes them into more complex structures

13. ribosomes Smooth ER Rough ER cytoplasm nucleolus nucleus

14. 5.Golgi Apparatus • Description: layers of membranes • Function: packaging area of the cell • Sorts & prepares protein compounds • Ships proteins where needed • Storage within cell • Out of cell

15. ribosomes Smooth ER Rough ER nucleus cytoplasm nucleolus Golgi apparatus

16. 6.Lysosomes • Description: small sacs of digestive enzymes • Function: breakdown macromolecules & digest old organelles (“clean up crew”)

17. lysosome ribosomes Smooth ER Rough ER nucleus cytoplasm nucleolus Golgi apparatus

18. Don’t Forget: Summary • Add a horizontal line to the bottom of you cornell notes • Tonight: write a 3-5 complete sentence summary of our lecture today

19. AVID Thinking Strategy: Tattoo or Body Art • You are in charge of developing a tattoo to allow the world to know about one of the discussed organelles. 1. The centerpiece of the tattoo must be a slogan representing the organelle. 2. The surrounding artwork (minimum of 3 colors) must represent the organelle’s function 3. The artwork must be suitable for all ages and appropriate for viewing in all social situations. 4. 5-7 complete sentence explanation of how the artwork represents the organelle AND the best location for the tattoo on the body

20. Warm Up: Wednesday, Sept 19 • Reminder: write in your 3 brad folder • List 2 organelles we discussed in class yesterday and give their function.

21. Objectives • Define the term organelle. • List organelles found in living cells • Identify the important roles organelles play within a cell. • Compare and contrast animal and plant cells. • Label organelles in plant and animal cells.

22. 7.Vacuoles • Description: single membrane fluid filled space within cell • Very large in plant cells • Small in animal cells • Function: maintains fluid, removes waste (storage unit of cell)

23. lysosome ribosomes Smooth ER Rough ER nucleus cytoplasm nucleolus vacuole Golgi apparatus

24. 8.Mitochondria • Description: large organelle with folded internal membranes • Has 2 membranes • Contains own DNA • Function: makes energy for the cell

25. lysosome ribosomes Smooth ER Rough ER nucleus cytoplasm nucleolus vacuole Golgi apparatus mitochondria

26. 9.Chloroplast • Description: organelle contained by 2 membranes occurring in a variety of shapes & sizes • Only occur in plant cells • Contains own DNA

27. 9.Chloroplast • Function: site of photosynthesis • Traps energy from the sun • Converts energy to chemical energy

28. lysosome ribosomes chloroplast Smooth ER Rough ER nucleus cytoplasm nucleolus vacuole Golgi apparatus mitochondria

29. 10.Cytoskeleton • Description: jelly like rectangle that contains thread-like microtubles • Function: support structure & transportation system of cell

30. lysosome ribosomes chloroplast Smooth ER Rough ER nucleus cytoplasm nucleolus cytoskeleton vacuole Golgi apparatus mitochondria

31. 11.Centrioles • Description: rod shaped bodies near the nucleus • Function: help separate chromosomes during cell division (mitosis)

32. lysosome ribosomes chloroplast Smooth ER Rough ER nucleus cytoplasm nucleolus centrioles cytoskeleton vacuole Golgi apparatus mitochondria

33. 12.Cell Membrane • Description: outer layer of the cell • Mainly composed of lipids & proteins • Lipid bi-layer & embedded proteins • Function: regulates what enters & leaves the cell

34. lysosome ribosomes chloroplast Smooth ER Rough ER nucleus cytoplasm nucleolus Cell membrane cytoskeleton vacuole Golgi apparatus mitochondria

35. 13.Cell Wall • Description: fairly rigid layer that surrounds the outside of the cell membrane • Found only around plant cells • Give plant cells square shape • Function: provides structure, support & protect for cell

36. Don’t Forget: Summary • Add a horizontal line to the bottom of you cornell notes • Tonight: write a 3-5 complete sentence summary of our lecture today

37. AVId Thinking Strategy:Toy Design • Apply your knowledge of organelles to design the best selling toy of the season. It must be able to fit into a standard backpack & not cause serious bodily injury as part of normal use. • What is the name of the toy? • What age group is the toy designed to reach? • Make an illustration of the toy(minimum of 3 colors). • Use 3-4 complete sentences to describe how the toy employs on of the organelle’s functions. • List the most fun feature(s) of the toy.

38. Warm Up: Thursday, Sept 20 • Reminder: write in your 3 brad folder • What macromolecules make up the cell membrane? • What is the function of the cytoskeleton?

39. Objectives • Define the term organelle. • List organelles found in living cells • Identify the important roles organelles play within a cell. • Compare and contrast animal and plant cells. • Label organelles in plant and animal cells.

40. What is the difference? Plant vs Animal cells

41. What is the SAme? Plant vs Animal cells

43. Quiz Tomorrow • In Class Today: • Complete animal & plant cell handouts • Color in and label organelles on cell drawings • Tonight: • Review labeled handouts for plant and animal cells • Review functions of organelles
