Chapter 15

The sexual apparatus in the watermolds has not been accorded the same degree of subcellular examination that characterizes the fine structure studies on their asexual reproductive mechanism. Nevertheless, the work that has been done demonstrates that the sexual structures are certainly amenable to ultrastructural analysis. Transmission electron microscopy has greatly expanded that knowledge which limited cytological methodology had discovered about the morphology of the sex cells of the watermolds, and has, as well, disclosed previously unsuspected events accompanying their development. However, much is yet to be learned of the structure, location, displacement, and function of organelles in the morphogenesis of the sexual system of watermolds.
