Chrysophytes; Algae--Ultrastructure


Information on the fine structure of naturally occurring cells of Chrysosphaerella brevispina and C. longispina is given and some new data are presented. The ultrastructure is generally typical for the Chrysophyceae although both perinuclear cisternae and cytoplasmic endobiotic bacteria occur. A paraflagella rod occurs in the photoreceptor area of the short, second flagellum. Siliceous scale and bristle origin are illustrated.
