Presentation Transcript

  1. Cell Organelles

  2. 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.

  3. nucleus cytoplasm nucleolus

  4. Organelles • Specialized structures within a living cell • Parts of the cell that act like specialized “organs”

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

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

  7. 3.Nucleus • Function: control all activitiesof the cell (acts like a brain) • Chromatin = coiled up DNA in nucleus • Nuclear Envelope = surrounds and protests the nucleus • Nucleolus= dark spot in the middle of the nucleus that helps make ribosomes

  8. nucleus cytoplasm nucleolus

  9. 4.Ribosomes • Description: Particles made up of RNA & proteins. Found either: • Free in the cytoplasm • Attached to other organelles. • Function: make proteins

  10. ribosomes nucleus cytoplasm nucleolus

  11. Eukaryotic Cell Organelles and Function • Endoplasmic Reticulum (ER) • Nickname: “Roads” • Function: The internal delivery system of the cell (main transport system of the cell).

  12. Endoplasmic Reticulum • 2 Types: • Rough ER: • Rough appearance because it has ribosomes • Function: helps make proteins, that’s why it has ribosomes • Smooth ER: • NO ribosomes • Function: makes fats or lipids

  13. ribosomes Smooth ER Rough ER cytoplasm nucleolus nucleus

  14. Eukaryotic Cell Organelles and Function Golgi body: • Function: packages, modifies, and transports materials to different location inside/outside of the cell • Appearance: stack of pancakes

  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 or janitors”)

  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. 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.

  21. 7.Vacuoles • Function: stores water (storage) • Very large in plant • Small in animal cells • When there is no water, the plant wilts

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

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

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

  25. 9.Chloroplast • Function: site of photosynthesis • Traps energy from the sun • Converts energy to chemical energy • Only occur in plant cells • Contains own DNA

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

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

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

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

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

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

  32. 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

  33. 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

  34. 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.

  35. 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.

  36. What is the difference? Plant vs Animal cells

  37. What is the SAme? Plant vs Animal cells

  38. 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

  39. Thinking Strategy #21: Diamante Poem • This poem follows a very specific pattern. There are 7 lines that will make the shape of a diamond. • Draw the following diamond on the next blank page in your notebook.

  40. Thinking Strategy #21: Diamante Poem • This poem follows a very specific pattern. There are 7 lines that will make the shape of a diamond. • Line 1: topic (noun 1) • Line 2: 2 describing words for noun 1 (adjectives) • Line 3: Three action words (“-ing”) for noun 1 • Line 4: 4 words. 2 words about the topic & 2 words opposite to those in line 2. • Line 5: 3 action words for the ending noun 2. • Line 6: 2 words to describe noun 2. • Line 7: Ending noun 2. (opposite of line 1)
