Cell Organelles

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