Preparing Hydra for Freeze-Fracture and Freeze-Etchingid freezing of tissues, either with or without partial sublimation of ice (etching). By evaporating a film of pure carbon on the exposed surface, a replica of the cell surface is obtained which reveals its intimate contours. Contrast is obtained by shadowing the exposed surface with evaporated plati
