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.

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.

Chlamydomonas (clam-ee-dough-moan-ass) a common volvocid (green alga) flagellate. Cells vary in shape from elongate to rounded, this being one of the more elongate cells. With a cell wall, a cup-shaped chloroplasts with chlorophyll B, a red eyespot located external to the plastid, and two equal flagella emerging from the anterior pole of the cell. These cells undergo a form of sexual reproduction referred to as conjugation in which two similar to near similar cells fuse and exchange genetic information. Animations by Rosemary Arbur of flagellar beat patterns are available
here. Differential interference contrast. Material from Nymph Creek and Nymph Lake, thermal sites within Yellowstone National Park, photograph by Kathy Sheehan and David Patterson.

Portrait (lateral view) of the Prasinophyte, Nephroselmis olivacea (Stein, 1878). Cell outline is reniform. Strongly laterally compressed. Two unequal flagella insert at an invagination in midbody. The shorter flagellum is directed anteriorly during swimming, the longer trailing. Single cup-shaped chloroplast with pyrenoid; eyespot (not well seen here) lies on the chloroplast in front of the short flagellum. Freshwater species with a contractile vacuole (seen near flagellar insertion in this image). The cytoplasm contains refractile particles of starch storage compounds. Cells covered with up to 7 types of scales seen by electron microscopy. The flagella are covered by a complex arrangement of heteromorphic scales. Collected from freshwater pond near Boise, Idaho July 2004. DIC optics.

Portartit of the volvocid flagellate, Volvulina steinii Playfair,1915. The cells are hemispherical with the flattened face of each toward the exterior in contact with the thin investing gelatinous envelope.The inner limit of the envelope is visible here. the thickness of the investing layer of the gelatinous envelope is indicated here by debris adhering to its exterior surface.Each of the 16 cells in the colony bears two equal-length flagella (seen here in the cell at 12 o'clock). Only cells at the "anterior" end of the colony have eyespots. each cell has two contractile vacuoles (seen here in the cell at 12 o'clock.Collected from a temporary rainwater puddle on a grass lawn in Boise, Idaho In vivo portrait of the volvocid flagellate, 43°36'49.03" N 116° 13' 23.77" W elev. 2674 ft. elev. 2674 ft.
