Scale bar indicates 5 m.Sample from a pond in Lemkendorf on the isle Fehmarn (Baltic Sea). The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Canon EOS 70D.For permission to use of (high-resolution) images please contact postmaster@protisten.de.

This chlorophyta has a dimpled cell wall surface, what is shown by manually stacking technique using 17 high resolution DIC frames. The scale bar indicates 10 m. Collected from bottom sediments of a rain storage reservoir in Kiel (Schleswig-Holstein, Germany). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.For permission to use of (high-resolution) images please contact postmaster@protisten.de.

Portrait of Lobomonas stellata (Chodat), a volvocid flagellate. The ellipsoid to pear-shaped protoplast is separated from the cell wall by a space containing gelatinous material. The cell wall has irregularly spaced conical protrusions. There is one large cup-shaped chloroplast. A pyrenoid is located posteriorly. A peripheral stigma is located in the anterior 1/3 of the cell. Two equal flagella are about the length of the cell body. From freshwater pond near Boise, Idaho.DIC.

Portrait of antherozoid (motile male gamete structurally similar to the zoospore but smaller) of the aquatic filamentous green alga Oedogonium. Reproduction in Oedogonium may be asexual, by means of large flagellated zoospores (motile reproductive cells capable of transformation into another developmental stage but incapable of sexual fusion) or o?¶gamous with fertilization of o?¶gonia by antherozoids (motile male gametes structurally similar to zoospore but smaller). O?¶gonia appear as large globular cells interposed between the cylindrical vegetative cells of the filament. Fertilization occurs after the antherozoid penetrates a specialized receptive area of the o?¶gonial cell wall. Collected from freshwater pond near Boise, Idaho in October 2003. DIC optics.

Portrait (lateral view) of the chaetophoralean alga, Aphanochaete repens (Braun, 1849). A. repens is epiphytic on filamentous algae (in this case Oedegonium). The cells are cylindrical to cuboid, some bearing one clear seta with a bulbous base. The cells arrange themselves in files with short branches along the long axis of their host algal filament. Collected from a freshwater pond near Boise, Idaho June 2004. DIC optics.

In vivo portartit of slightly compressed volvocid flagellate, Volvulina steinii Playfair,1915 showing the two contractile vacuoles. The single nucleus of several cells is visible. Only the "anterior" cells of the colony have red eyespots. Collected from a temporary rainwater puddle on a grass lawn in Boise, Idaho. 43°36'49.03" N 116° 13' 23.77" W elev. 2674 ft. March 2006. DIC.
