Abstract

A method was employed whereby it was possible to determine the growth pattern of hydra without using the traditional techniques of grafting and vital staining. It has been shown that hydra possess a growth region just below the hypostome where constant cell proliferation renews the tissues of the animal completely every few weeks.
