  1. PLANT AND ANIMAL CELLS

  2. Early Scientists’ Contributions: Record notes on pages 2 and 3

  3. Anton van Leeuwenhoek • First compound light microscope

  4. Robert Hooke • Coined the term “cell”

  5. Matthias Schlieden • All plants are made of cells

  6. Theodor Schwann • All animals are made of cells

  7. Rudolf Virchow • Cells can only arise from pre-existing cells

  8. Cell Theory: Record on page 4 • All organisms are made up of one or more cells. • The cell is the basic unit of organization of all organisms. • All cells come from other cells all ready in existence.

  9. Building Blocks of Life from Large to Small: Record on page 5 • Biosphere • Ecosystem • Community • Population • Individual • Organs 7. Tissues 8. Cells 9. Molecules 10. Atoms 11. Quarks

  10. Cell Functions: Record on pages 8 – 11 in burrito journal

  11. CELL WALL: PLANT • Function:Gives the cell most of its support and structure • A thick, rigid membrane that surrounds a plant cell • Bonds with other cell walls to form the structure of the plant Analogy: Like a brick wall

  12. CELL MEMBRANE • Function:Semi permeable, allowing some substances to pass into the cell and blocking others. • Thin layer of protein and fat that surrounds the cell Analogy: Like a gate

  13. Chloroplast • Function: Where photosynthesis takes place • An elongated or disc-shaped organelle containing chlorophyll Analogy: I am sweet like a mint gumdrop.

  14. Cytoplasm • Function:Where the organelles are located. • Analogy: Like cherry Jello.

  15. ENDOPLASMIC RETICULUM • Function:transports materials through the cell • Rough ER is covered with ribosome's that give it a rough appearance Analogy: Like a train.

  16. Golgi Bodies • Function:Golgi bodies are the packaging and secreting organelles of the cell. • Are stacks of membrane-covered sacs that package and move proteins to the outside of the cell. Analogy: Like Amazon

  17. Lysosome • Function:Where the digestion of cell nutrients takes place • Also called cell vesicles • Spherical organelles surrounded by a membrane • They contain digestive enzymes Analogy: Like a garbage disposal

  18. Mitochondria • Functions:Powerhouse of the cell. Where energy of the cell is released. • Spherical to rod-shaped organelles with a double membrane • Membrane is infolded many times, forming a series of projections (called cristae) Analogy: Like a battery

  19. Nucleus:The Manager • Function:Controls many of the functions of the cell • Spherical body containing many organelles, including the nucleolus • Contains DNA (in chromosomes) • Surrounded by the nuclear membrane Analogy: Like a boss or CEO

  20. Ribosome's • Function:Small structures in the cytoplasm that create proteins. • Ribosome's are either free floating in the cytoplasm of a cell or attached to endoplasmic reticulum in a cell. • Analogy: Like BBQ ribs

  21. Vacuole • Function: a vacuole is a temporary storage space for the cell • Fluid-filled, membrane-surrounded cavities inside a cell • Fills with food being digested and waste material that is on its way out of the cell Analogy: Like a suitcase

  22. Plant Cell

  23. Cross Section: Animal Cell

  24. Edible Plant and Animal Cells

  25. More Edible Cells

  26. Material Suggestions • pieces each of round and square bread (cell) • honey (cytoplasm) • Marshmallows (vacuoles) – 1 large white for plant, 5 small yellow for animal • Straight Pretzels (cell wall) • Wrapped Hard Candies (nucleus) • jelly beans (mitochondria) • green Marshmallows (chloroplasts) • Twizzlers (Endoplasmic Reticulum) • Smarties (Golgi Bodies) • Gum Drops (Lysosomes) • jar of Sprinkles (Ribosomes) • aluminum foil (cell membrane)
