The development of microscopes allowed scientists to investigate living things in greater detail. Through many investigations, scientists found evidence that all living things are made of one or more basic units that divide to form new units. Scientists used their evidence to explain the relationship between these "building blocks of life" and the organisms to which they belong. What is this explanation called?

The cell theory

Explanation:

The explanation of the relationship between the building blocks of life based on the evidence gathered by scientists from studying these building blocks is called the cell theory.

Many scientists study the building blocks. One of the earliest scientists to study these blocks gave them the name 'cells'. Thereafter, several other scientists studied different aspects of the cell and, eventually, the cell theory was propounded. There are three aspects to the theory:
