Method Hydra were placed into embryological salt dishes with just sufficient medium so that they could fully extend, and then were quickly flooded, to prevent contraction, with Lavdowsky’s fixative
Comments Value for fed and unfed animals. Feeding induces an additional 10-15 percent of cells per day. FedAssuming all cells are mitotically active, these mitotic rates yield estimates of the epithelial cell cycle of about ‘7 days in unfed animals and about 3-4 days in fed animals
