Tribonema (tribe-owe-knee-ma) is a xanthophyte, a group of stramenopiles with chloroplasts. Xanthophytes may adopt a variety of body forms, and the normal form for this genus is the filament. Cell walls often built from H-shaped units, and these overlap in the middle of a cell. Plastids usually discoid, yellow green. Differential interference contrast.

Silicious processes (the labiate and the occluded ones) are visible. Scale bar indicates 25 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.
