Scale bar indicates 50 m.Sample from a pond on the isle of Hiddensee (German Baltic Sea). The image was built up using several photomicrographic frames with manual stacking technique. The images were taken using Zeiss Universal with Olympus C7070 CCD camera.For permission to use of (high-resolution) images please contact postmaster@protisten.de.

Eudorina (you-door-ine-a) is a colonial volvocid - motile green alga. In this case 16 cells are embedded in a sphere of common mucus. Each individual cell has two flagella, and a cup-shaped chloroplast - a bit like a Chlamydomonas cell. There are a number of related genera which form colonies using mucus as a common matrix, but they differ in the numbers of cells involved, how tightly packed they are, and the shape of the colony. Differential interference contrast.

This image illustrates the way that a daughter colony of tightly packed cells is formed within a parental colony. Phase contrast.

Eudorina, a motile colonial volvocid flagellate. Colonies may be cylindrical, elliptical or spherical as seen in this image. Colonies may be composed of 8 to 128 cells. This colony is composed of 16 individuals embedded in a clear gelatinous matrix. Two equal length flagella protrude through the matrix from each cell. Cells may be arranged in tiers or more randomly as seen here. One large bright green cup-shaped chloroplast. Small red stigma. Sexual and asexual reproduction occurs. From temporary rainwater pool in grass field near Boise, Idaho. Phase contrast.
