Melosiraceae

Melosira (mell-o-sigh-ra) is a centric diatom. The cells are like old-style hat boxes, or old-style pill boxes, or like petri-dishes. In Melosira, many cells are joined end to end to create a filament. The less substantial rings on the lower image are where the two halves of the frustule are joined together by the girdle bands, the more visible connections are where two cells are joined together. Each cell has a radial symmetry. As with other diatoms, plastids have chlorophylls a and c and so have a yellow brown colour. The lower picture reveals the individual disc-shaped plastids. Phase contrast.

Melosira (mellow-sire-a) nummuloides, filament forming centric diatom, with multiple small plastids within the cell. Dark ground illumination. Leptosiropsis (leapt-owe-sire-op-sis) torulosa, green alga with organic wall that is produced in layers. Phase contrast microscopy. data on this strain.

Colony with epibiotic bacteria chains. Scale bar indicates 100 µm. The image was built up using several photomicrographic frames with manual stacking technique.  Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
