Found out that plant and animal cells are similar. This led to the formulation of the 3 cell theories. G EN ERA L BIO LO G Y 1 – FIRST Q UA RT ER  CELL THEORY (OLD) 1. The cell is the unit of structure, physiology, and organization in living things. 2. The cell is the building block in the construction of every organisms. 3. Cells form by spontaneous generation.
