The component of the modern cell theory that was not part of the original cell theory is: **All cells are similar in composition and metabolic activities.**

The original cell theory, formulated in the mid-19th century, included the following three principles:

1. All organisms are made of cells.
2. The cell is the basic unit of structure and function in living things.
3. All cells arise from preexisting cells.

The additional component regarding the similarity in composition and metabolic activities among cells was added in later developments of the cell theory, leading to what we now refer to as modern cell theory.
