C. New cells come only from pre-existing cells by cell division.
D. Cells are the smallest unit of living organisms, and new cells form from pre-existing cells by cell division.
E. All living organisms are composed of one or more cells, cells are the smallest units of life, and new cells come only from pre-existing cells by cell division.
