Transcript

  • 1. Cell Project Sean Dixon
  • 2. Who Discovered Cells
    • Robert Hooke discovered the cell in England in 1665.
  • 3. Cells
    • There are two types of cells, animal and plant cells.
    • They have similar characteristics but are not the same
  • 4. Plant Cell
    • Plant cells have two things animal cells do not have, a cell wall and chloroplast.
    • They have a large central vacuole enclosed by a membrane, the tonoplast.
  • 5. Animal Cell
    • These cells are the cells that make up humans and animals.
    • The largest known animal cell is an ostrich egg
  • 6. Inside of Animal Cells
    • Inside of animal cells are tiny organs called organelles.
    • They are the nucleus, mitochondria, ribosomes, rough/smooth endoplasmic reticulum, golgi apparatus, centriole, plasma membrane, vacuole, and lysosome.
  • 7. Vacuole
    • Lysosomes store water and food for the cell.
    • They take up a large amount of space in the cell.
    • Mostly found in plant cells.
  • 8. Lysosomes
    • Lysosomes dissolve wasted cells and food for energy for the cell.
    • They are very small but very efficient.
    • Lysosomes fuse with vacuoles and dispense their enzymes into the vacuoles.
  • 9. Rough/Smooth ER
    • Transports proteins to be used in the cell membrane
    • Endoplasmic Reticulum is found in all eukaryotic cells
    • First seen by Keith Porter, Albert Claude, and Ernest F. Fullam in 1945.
  • 10. Nucleus
    • The “brain” of the cell.
    • Contains specific instructions for reproducing.
    • Found in most eukaryotic cells
  • 11. Mitochondria
    • Mitochondria are thought to be descended from ancient bacteria, range from 1-10 millimeters in size.
    • Generate most of the cell’s supply of ATP.
  • 12. Golgi Apparatus
    • Also called the Golgi body , Golgi complex , or dictyosome .
    • Package and processes proteins and lipids.
  • 13. Cell Membrane
    • Also called the plasma membrane , plasmalemma or “phospholipid bilayer.”
    • Surrounds the cytoplasm and cell.
