• Cells are too small to be seen by the naked eye, but can be seen by the microscope
• Scientist were now able to study cells in detail
• The first person to describe the cell using a microscope was Robert Hooke when he examined a thin slice of cork and noticed some small structures
• Cell membrane


  • AKA Plasma membrane

• Nucleus


  • Contains the DNA
  • Appears circular or oval shaped
  • Brain of the cell as it controls all the activities
• Parts of the cell that perform specific functions

  • Size around 200 mm
• Ribosomes


  Carry out protein synthesis
• Golgi Bodies


  Responsible for transporting and packaging some organelles
• Cytoplasm
