existing
The idea that all cells must come from pre-existing cells is known as cell theory. This theory states that cells are the basic unit of life and that all living organisms are composed of cells. It also proposes that cells arise from pre-existing cells through cell division.
The Cell Theory stats that all cells come from pre-exsisting cells
Rudolf Virchow said that all cells come from existing cells.
The cell theory states that all living organisms are composed of one or more cells, cells are the basic units of structure and function in organisms, and all cells come from pre-existing cells through cell division.
Cells must have a specific shape and size is not a principle of cell theory. Cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
All cells come from a stem cell, which is an unspecialized cell that gives rise to a specific specialized cell, such as a blood cell. These cells differentiate and give rise to the various kinds of cells we have in our body.

The cell theory states that all cells come from pre-existing cells. This means that new cells are produced through the division of existing cells.
