Cell theory.

• The basic principles of the cell theory are
• All organisms are made of cells that resemble
  each other by having internal structures and a
  boundary
• These cells are always formed by the division of
  pre-existing cells
• Cells contain inherited information which
  determines their activity
• Given suitable conditions, cells are capable of
  independent existence
• Can you name the 7 characteristics all living
  things share?

7
Cell Structure

• Given these principles of cells, biologists
  recognise two types of cellular structure
• Prokaryotic cells (before the nucleus)
• Eukaryotic cells (with a nucleus)
• Virus particles do not fulfil the criteria of the
  cell theory and so are regarded as being
  non-cellular. Some texts may refer to their
  structure as being akaryotic (without a nucleus)
