Research on the Genus Fosliella (Rhodophyta, Corallinaceae): Structure, Ultrastructure and Function of Transfer Cells

Abstract
Observations made with both transmission and electron microscopy and with vital (Chlorotetracycline) and nonvital (carmine) elective stains are consistent with the hypothesis that the epithallial cells in Fosliella act as transfer cells. Some aspects of the morphology and function of these epithallial transfer cells are described and related to the constant renewal of the whole epithallial layer.
