Cell Theory

• The theory is one of the major theories in
  science because it tells the most important
  description of a cell. It is also very important
  because it was not observations of one person,
  but many scientists. Some of them were Schleidan,

  basic unit of structure and function in all
  organisms.3. All cells come from cells that
  already exist.
