    Cell Organelles Cell Organelles Presentation Transcript

    • 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.
    • Intro to Cell Vocabulary Fancy Names For Simple Things
    • Cells
      • Cells are the basic unit of all living things (organisms).
      • If it is alive it has cells!
    • 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
    • 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! 
    • When you hear the new vocabulary…just think of a Turtle
    • 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.
    • 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.
    • Mitochondria
      • Mitochondria is an ORGANelle that breaks down food to make energy.
      • Mitochondria is like a turtle’s stomach.
    • Nucleus
      • The nucleus controls the cell.
      • The nucleus is like the turtle’s brain.
    • Nucleolus
      • The nucleolus can be found inside the nucleus.
      • It makes ribosomes for the cell.
    • 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).
    • 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.
    • 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?
    • 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?
    • Golgi body or Golgi apparatus
      • The golgi body is the “post office” for the cell.
      • It packages substances for movement out of the cell.
    • 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”!
    • 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!)
    • 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.
    • 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?
    • What’s the Difference?
      • So what are THREE things that plant cells have that animal cells don’t?
      ? Chloroplasts, Cell Walls & a Water Vacuole
    • What would happen if animals had Chloroplasts?
    • Congratulations
      • You now know all the vocabulary for cells
    • Compare and Contrast Plant and Animal Cells using a Venn Diagram
    • 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.
