Cell Organelles Presentation Transcript

  • 1. Objective: You will….
    • compare and contrast animal and plant cells in terms of their cellular structure.
    • Summarize the functions of organelles found in animal and plant cells.
  • 2. Intro to Cell Vocabulary Fancy Names For Simple Things
  • 3. Cells
    • Cells are the basic unit of all living things (organisms).
    • If it is alive it has cells!
  • 4. Two “Classes” of Cells
    • There are 2 classes of cells. There are only two differences between Plant & Animal cells…try to spot them by the end of the show.
    Plant cells Animal Cells
  • 5. Cell Differentiation
    • There are only 2 classes of cells (plant/animal), but there are many kinds of cells in each class. Each kind of cell has a DIFFERENT job to do…it specializes.
    I’m a heart cell! I’m a nerve cell! I’m a Prison Cell! 
  • 6. When you hear the new vocabulary…just think of a Turtle
  • 7. Cell Membrane
    • The cell membrane holds the cell together and allows nutrients in the cell.
    • It’s just like a turtle’s skin.
    • The cell membrane is on the edge of a cell.
  • 8. Cytoplasm
    • Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It anchors the ORGANelles.
    • Cytoplasm is like the turtle’s blood and other liquids in which the organs bathe.
  • 9. Mitochondria
    • Mitochondria is an ORGANelle that breaks down food to make energy.
    • Mitochondria is like a turtle’s stomach.
  • 10. Nucleus
    • The nucleus controls the cell.
    • The nucleus is like the turtle’s brain.
  • 11. Nucleolus
    • The nucleolus can be found inside the nucleus.
    • It makes ribosomes for the cell.
  • 12. Chromosomes (Chromatin)
    • Chromosomes are inside the nucleus and are made of genes (DNA).
    • Genes decide the cells traits and activities (heart rate, eye color, tongue rolling).
  • 13. Nuclear Membrane
    • The nuclear membrane allows substances to pass in and out of the nucleus.
    • It surrounds the nucleus (the brain) like the turtle’s skull…protects it.
  • 14. Endoplasmic reticulum
    • The endoplasmic reticulum is the “highway” of the cell.
    • It moves substances throughout the cell like the blood vessels in a turtle move blood and nutrients throughout its body.
    Did someone say blood?
  • 15. Ribosomes
    • The ribosomes make proteins for the cell.
    • Think of the turtles “ribs” which are covered with yummy protein-filled meat.
    • Ribosomes can be found on the R OUGH endoplasmic reticulum.
    Turtle soup?
  • 16. Golgi body or Golgi apparatus
    • The golgi body is the “post office” for the cell.
    • It packages substances for movement out of the cell.
  • 17. Vacuoles
    • Vacuoles are compartments in the cytoplasm where food and chemicals are stored.
    • In animal cells, lysosomes are vacuoles that break down substances for the cell.
    Just call me “ Count Vacula”!
  • 18. Cell Wall
    • Cell Walls are only in plant cells.
    • They make the cell strong and rigid.
    • They are like a turtle’s shell (but only plants have them…that’s why grass stands straight up!)
  • 19. Plant vacuole
    • The plant vacuole is also called the water vacuole because it stores water for the plant.
    • It’s like the turtle’s own private pool.
  • 20. Chloroplasts
    • Chloroplasts are only in plant cells.
    • They contain chlorophyll, which is a pigment that captures sunlight so that food can be made.
    • Chlorophyll is green in color…so any plant that is green has chloroplasts.
    I’m green…do I have chloroplasts?
  • 21. What’s the Difference?
    • So what are THREE things that plant cells have that animal cells don’t?
    ? Chloroplasts, Cell Walls & a Water Vacuole
  • 22. What would happen if animals had Chloroplasts?
  • 23. Congratulations
    • You now know all the vocabulary for cells
  • 24. Compare and Contrast Plant and Animal Cells using a Venn Diagram
  • 25. Thanks to www.worldofteaching.com for providing me with the slides for this powerpoint. I added a few more slides and sound bites to enhance my teaching of the organelles.
