FINE STRUCTURE OF A DIATOM CENTROSOME.
The centrosome of the diatom Surirella ovalis is a dense spherical structure 500 mmicro in diamneter with filaments 15 mmicro in diamneter connected to it. The interior is filled with uniform granules but does not contain a typical centriole or clear area. The filaments emanating from it resemble the filaments of the mitotic apparatus, but they are present during interphase and appear to terminate at pores in the nuclear envelope.
