Transcript

  • 1. What the Cell?
  • 2. Cell
    • Cell - smallest, independent unit of life!
    • - made up of organelles – nucleus, mitochondria, cell membrane, etc.
  • 3. 1. Plasma Membrane
    • Cell Membrane – surrounds the entire cell.
    • - “Semi-permeable” – lets only certain materials into and out of cell.
    • - Lipid “Bilayer” -
    • 2 layers of lipids.
    Proteins Lipids Receptors
  • 4. 2. Cytoplasm
    • Cytoplasm – fluid “jelly” material that fills the cell.
    • - made up mostly of water !
  • 5. 3. Nucleus
    • Nucleus – controls all activities of the cell.
    • - contains chromosomes & DNA.
    • - in charge of cell division
    Nucleus
  • 6. 4. Mitochondria
    • Mitochondria – makes the cell’s ATP (energy).
    • - Carries out Cellular Respiration .
  • 7. 5. Endoplasmic Reticulum
    • E.R. – pathways which transport and make materials.
    • - Rough ER – has ribosomes.
    • - Smooth ER – no ribosomes.
  • 8. 6. Ribosome
    • Ribosome – synthesizes proteins for the cell.
    • - can be attached to Endoplasmic Reticulum
    • or “free” floating in the cytoplasm.
  • 9. 7. Vacuole
    • Vacuole – “sack” that stores materials.
    • a. Food vacuole – stores food
    • b. Contractile vacuole – pumps water out
  • 10. 8. Golgi Bodies
    • Golgi Bodies – package and ship materials around cell.
  • 11. 9. Lysosome
    • Lysosome – “ sack” containing digestive enzymes.
    • - destroys wastes, food, bacteria, etc.
  • 12. Plant Cells Vs. Animal Cells
  • 13. Plant Cells
    • 1. Cell wall – provide support and protection for the cell.
    • - lies OUTSIDE cell membrane.
    • - makes plant cells rectangular.
    Cell wall “outer layer”
  • 14.
    • 2. Chloroplast – uses energy from the sun to make simple sugars (glucose).
    • - contain chlorophyll which captures sunlight.
    • - carries out photosynthesis :
    • 6 H 2 O + 6 CO 2 ------> C 6 H 12 O 6 + 6 O 2
    • ( water ) ( carbon dioxide ) ( glucose ) ( oxygen )
  • 15. Animal Cells
    • Centriole – cylindrical “sticks” that help in cellular division.
  • 16. Single-Celled Vs. Multicellular
    • Single-cell – organisms that are made of only one cell.
    • - capable of metabolism and homeostasis.
    • Ex: bacteria, paramecium, etc.
  • 17.
    • Multicellular – organisms that are made up of many, many cells.
    • - Tissues – group of cells working together.
    • - Organs – group of tissues working together. (Ex: Stomach)
    • - Organ systems – group of organs working together. (Ex: Digestive)
    • Ex: Humans, plants, animals
  • 18. Multicellular Organization Organelles Cells Tissues Organs Organ Systems Organism
  • 19.  
  • 20.  
  • 21. Microscopy and Cell Theory Microscopy and Cell Theory
  • 22.
    • - allows light to pass through specimen and uses two lenses to form an image.
    • - paves the way for cell theory .
    • - can observe LIVING specimens.
    Compound Light Microscope
  • 23. Electron Microscope
    • Observe specimens 1000X smaller than light microscopes.
    • - uses a beam of electrons.
    • - can NOT observe living specimens.
  • 24. Cell Theory
    • Cell Theory:
    • All living things are composed of cells.
    • Cells are basic units of structure and function in living things.
    • All cells arise from previous cells.
