Electron Microscopy of a normal human cell, The cell membrane, nucleus and the nucleolus are all
A typical animal cell is 10-20 μm in diameter, which is about one-fifth the size of the smallest particle visible to the naked eye. It was not until good light microscopes became available in the early part of the nineteenth century that all plant and animal tissues were discovered to be aggregates of individual cells. This discovery, proposed as the cell doctrine by Schleiden and Schwann.
