Resources: Cells and their parts
Cells Alive
Cell Tour
Cell Song

Day One:
  • What are cells?
  • KWL Chart
  • Cells are the Starting Point: All living organisms on Earth are divided in pieces called cells.
  • Plant Cells
    • Cell Wall - (plant cells), stronger than the cell membrane, both regulate what can go in and out of the cell (city)
    • Cell Membrane - city border (animal cells)

Day Two & Three:

  • Review cell membrane
  • Nucleus - the mayor of the city, the brain, controls all the activity
  • Nuclear Envelope/Membrane
  • Chromatin
  • Nucleolus
  • Review how to use a microscope
    • eye piece
    • lenses
    • stage with stage clips
    • tube
    • arm piece
    • illuminator
    • slide
    • slide cover
  • Look at onion cells

Days Four, Five and Six:
Cheek Cells
  • Ribosomes - manual labor, the brick layers, make the proteins for the nucleus The ribosomes carry out manual labor in the form of protein synthesis for the nucleus. They bring together all the raw ingredients to make the proteins
  • Endoplasmic Reticulum - highways for the city,Goods are manufactured and shipped to needed areas via the road system.
  • Cytoplasm - Cytoplasm is a semi-fluid substance (think gelatin) found inside the cell. The cytoplasm encases, cushions and protects the internal organelles. It is the cell landscape found in any space where organelles are not and therefore is much like the lawns and parks of our city.
  • Golgi Body - Like a post office, the golgi body is used for shipping those goods created by the ER and ribosomes to the rest of cell.Ch
  • Chloroplasts - solar energy plant- Chloroplasts are organelles found only in plant cells. Like a solar energy plant they use sunlight to create energy for the city. Chloroplasts are the site of photosynthesis a process in which the plant uses carbon dioxide, water and sunlight to create energy in the form of glucose for the plant cell.
  • Mitochondria- energy - are found in both plant and animal cells and is the site of cellular respiration. Creates energy for the cell.
  • Lysosomes - recycling and waste disposal - The lysosomes are digestive sacs that can break down macromolecules in the cell using the process of hydrolysis. The digestion is carried out with lysosomal enzymes found in the lysosome. Like waste disposal in a city, lysosomes help keep excessive waste from building up in the cell.
  • Vacuoles - Warehouses- Think of these membrane sacs that have a variety of functions as containment units for anything in excess in a city. They can hold many substances from organic molecules to simple excess water.
