Welcome to the electronic frontier classroom of the 21st Century.  This laboratory practical is found on the web site "Mitchell's Cosmic Adventure" under the heading "Biology", subheading "Experiments", and Inquiry Lab: Observing Cells".
   The cell is the basic unit of all living things. All organisms are made up of at least one cell. Large organisms, such as humans, are made  up of trillions of cells.  I hope you enjoy learning and comparing animal verse plant cells during this experiment.
