Endogenous multiplication (Biol.), a method of cell
formation, seen in cells having a cell wall. The nucleus
and protoplasm divide into two distinct masses; these in
turn become divided and subdivided, each division becoming
a new cell, until finally the original cell wall is
ruptured and the new cells are liberated (see
Segmentation, and Illust. of Cell Division, under
Division). This mode of growth is characteristic of many
forms of cells, both animal and vegetable.
