At the ripening period of the germ cell the members of each pair of chromosomes come together (fig. 49, e).
It is seen that the sexual cells are formed directly from the germ cell and contain no admixture from the cells of the body.
Spermatozoids are formed in the antheridium, and these enter the archegonium and fertilize the germ cell.
Each ontogeny (individual) begins in a minute germ cell, in which a small quantity of idioplasm is contained.
Organisms arise from a germ cell which consists of idioplasm and in turn they produce like germ cells.
