||"Electron micrographs showed that the
cytoplasm was restricted to a thin outer layer of
0.5- to 2-µm thickness. The
remaining 98% of the biovolume consisted of a liquid vacuole."
||"Most cells had diameters of 100 to 300µm
(Fig. 2B). Most cells in a chain were of a
similar diameter (Fig. 2C), but in some chains a
single cell occurred with a much larger diameter
of up to 750µm. These extremely large
forms also occurred as single cells (Fig. 1A).
The average Thiomargarita with a diameter of
180µm had a volume of 3X10^6µm^3, whereas
the largest observed cells had a biovolume of
