two cells

Description:

Thalassiosira (tha-lassy-owe-sire-a) eccentrica is one of the hundred or so species in the diverse and common genus of centric diatoms frequently found in marine waters. Some species can be very large. Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. The cell to the left is seen in girdle view, the one to the right in valve view. The margins of the valves give rise to a small number of fine chitinous filaments which are believed to function in flotation. These filaments are evident in arising from the cell to the right. With many small golden plastids. Phase contrast microscopy.
