Image of Ceramium diaphanum

Description:

Scale bars indicate 200 µm (1), 100 µm (2), 50 µm (3, 4), 25 µm (5).

Five images.

 

First:A dichotomously branching red alga of the genus Ceramium. The image shows axial cells that are partially surrounded by cortical cells (red belts). Filament hairs emerge from the cortical cells.Second:Close-up.Third:The cortical cells have round chloroplasts, while the chloroplasts of the axial cells are worm-shaped.Fourth:First cells of an adventitious shoot of Ceramium diaphanum , covered by a thick gelatinous layer (agar-like pectin).Fifth:This detailed view of a thallus segment shows cells of the two types found: a long axial cell (light, with worm-shaped rhodoplasts) and many small, round, reddish, cortical cells with their lens-shaped rhodoplasts. In the rounded outgrowth (tetrasporangium) three of the four cells with their nuclei are visible.
