What did Rudolf Virchow discover about cells?
Virchow’s greatest accomplishment was his observation that a whole organism does not get sick—only certain cells or groups of cells. In 1855, at the age of 34, he published his now famous aphorism “omnis cellula e cellula” (“every cell stems from another cell”).

Are all animals made of cells?
A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.

What was the cell theory given by Rudolf Virtue?
‘Omnis cellula e cellula,’ according to Rudolf Virchow, signifies that new cells are formed via the division of pre-existing cells. The discoveries of Rudolf Virchow have changed the cell hypothesis.

Which scientist added to the cell theory with his conclusion that cells must come from other cells?
Around 1850, a German doctor named Rudolf Virchow was studying cells under a microscope when he happened to see them dividing and forming new cells. He realized that living cells produce new cells through division. Based on this realization, Virchow proposed that living cells arise only from other living cells.
