He concluded that all cells come from preexisting cells.

Explanation:

Rudolf Virchow while building on the work of Theodore Schwann formulated a part of the cell theory which opined that cells arose from pre-exsiting cells which disproved the theory of spontaneous generation

Although this assertion has earlier been made by another scientist, Robert Remak in 1852, Schwann did not accept until later until after series of investigations.  Schwann was later accused of publishing the work of Robert Remak as his in 1855.

The other parts of the cell theory include:
