Chrysamoeba (cry-as-a-me-ba) mikrokonta, , a chrysophyte (stramenopile) with plastids and often occurring as an amoeboid organism. This detail of a flattened cell shows the two-lobed plastid, the carbohydrate (leucosin) storage vacuole (large irregular vacuole), a short flagellum and several fine pseudopodia. Phase contrast microscopy.

Synura sphagnicola, a colonial chrysophyte. Synonymous with Skadovskiella. Cells are joined at their posterior ends in the center of the colony. Cells are ovoid with two golden chloroplasts. There are two equal flagella less than 1 cell length. Siliceous scales with a unique ring form from which there is a rod-like projection cover the cell. A detached scale is seen in the center of this image. The scale structure is diagnostic for the species. A stigma is absent. Large vacuoles containing the glucopyranoside storage polymer, chrysolaminarin (leucosin) accumulate in the cytoplasm . The colonies swim with a slow rolling motion.From a polysaprobic temporary freshwater farm pond near Boise, Idaho. Differential interference contrast.Differential interference contrast optics.

Synura sphagnicola can be preferentially found in sphagnum ponds. Typical are the reddish oil droplets they bear in plasma. Sample from sphagnum pond Dosenmoor near Neumuenster (Schleswig-Holstein, Germany). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.

Chrysophyte. This cell was not identified to genus. It contains a plastid with chlorophylls a and c, a contractile vacuole is evident at the top of the cell, and the cell is surrounded in an organic wall. although these cells were common in some locations, no motile forms corresponding to these cells were seen. Differential interference contrast. Material from Nymph Creek and Nymph Lake, thermal sites within Yellowstone National Park, photograph by Kathy Sheehan and David Patterson.

Chromulina (crumb-you-line-a) nebulosa, a small chrysophyte (stramenopiles) with a single emergent flagellum. A second short flagellum is visible because cell division is beginning to occur (note the two chloroplasts) and a second flagellum has formed. -Phase contrast microscopy.

Dinobryon (dine-oh-bry-on) a mixotrophic stramenopile (chrysophyte) with one long flagellum and one short flagellum. When feeding heterotrophically, the beating of the long flagellum draws food towards the cell where it may be ingested. The cell also has brownish chloroplasts. It forms a flimsy tubular lorica.
