  • Nucleus
  • Cell Membrane
  • Cytoplasm
  • Chloroplast
  • Vacuole
  • Cell wall
• Nucleus

  Contains DNA to control cell function
• Cell membrane

  Controls what enters and leaves the cell
• Cytoplasm

  Where chemical reactions take place
• Vacuole

  Contains cell sap
• Cell wall

  Provides shape and support
• Chloroplast

  Contains chlorophyll. Carries out photosynthesis to make food.
• Mitochondria


  Carries out respiration to release energy from glucose.
• Cell Types


  • Plant cell
  • Animal cell
• Using a Microscope


  1. Use eyepiece lens x10

  2. Use objective lens x4, x10 or x40

  3. Turn focus knob to bring image into focus
• Overall magnification


  Eyepiece lens magnification x10 x Objective lens magnification
• Making a Slide


  1. Use a stain to make cell parts visible

  2. Use a mounted needle to lower the cover slip to avoid air bubbles

• Each part of the cell has its own specific function
• Nucleus


  Contains DNA and controls the cell activities
• Cytoplasm


  Where chemical reactions take place
• Chloroplast


  Absorbs light energy for photosynthesis
• Cell membrane


  Controls what enters and leaves the cell
• Mitochondria


  Where aerobic respiration takes place to release energy
• Cell wall


  Made of cellulose, gives the cell shape and support
• Vacuole


  Contains cell sap and keeps the cell firm
