Chlamydomonas is a green alga, common in freshwater habitats like Swan Lake. The cells are small with two flagella used for locomotion. A single red eyespot (stigma) is used to sense light levels and control the direction of 'swimming'. Animations by Rosemary Arbur of flagellar beat patterns are available

Scale bar indicates 50 m. Sample from the Domnental pond of Kronshagen near Kiel. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Olympus OM-D-E-M5 MKII.For permission to use of (high-resolution) images please contact postmaster@protisten.de.

Chlamydomonas (clam-ee-doe-moan-ass), a solitary volvocid (flagellated green algal cell). Cell surrounded by a cellulosic wall, with two similar flagella emerging from near the apex. The photosynthetic pigments are located within a cup-shaped chloroplast which has a large pyrenoid with associated polysaccharide materials located posteriorly. The nucleus is located within the cup. This image shows one anterior contractile vacuole. Animations by Rosemary Arbur of flagellar beat patterns are available
here.Phase contrast.

Chlamydomonas (clam-ee-doe-moan-ass), a solitary volvocid (flagellated green algal cell). Cell surrounded by a cellulosic wall. Cell damaged, no flagella. The photosynthetic pigments are located within a cup-shaped chloroplast which has a large pyrenoid with associated polysaccharide materials located posteriorly. The nucleus is located within the cup. This image shows the red eyespot to the right and two anterior contractile vacuoles. Phase contrast.

Portrait of Phacotus lenticularis, a volvocid flagellate. Lorica is composed of two shallow cup-shaped halves cemented together around the protoplast. Lorica surface is slightly rough and colored by minerals Two equal-length flagella protrude through an anterior pore in the lorica. Cup-shaped chloroplast. A stigma is present but not seen in these images. From a freshwater pond near Boise, Idaho. Brightfield.
