Portrait of Pediastrum duplex (Meyen, 1829 )demonstrating tufts of bristles protruding from the notch at the ends of the horns of peripheral cells (seen most clearly at one o'clock and 7 o'clock here). These bristles are thought to consist of proteinaceous microfilaments (see Scnepf,E. et al. J. Ultrastruct. Res. 72:367-379,1980). These nonmotile bristles may play a role in orienting the coenobia in the water column . DIC.
