Euglena gracilis (you-glean-a grass-ill-iss). Euglena is the iconic genus of euglenoid flagellates, and this is probably the most familiar of the species. The body of most euglenids is typically spindle-shaped, although two flagella arise in a pocket within the cell only one emerges (and sometimes none). The body can squirm, and the cell has one to many chloroplasts. At the anterior of the body a thin channel (flagellar canal) leads to the flagellar pocket, and alongside this is a contractile vacuole. A red eyespot or stigma is associated with the bottom of the flagellar canal. This image shows the nucleus (central). the region of the flagellar pocket as the lighter region to the right, the associated stigma, the single emergent flagellum, and several green chloroplasts. Phase contrast.

Euglena gracilis (you-glean-a grass-ill-iss). Euglena is the iconic genus of euglenoid flagellates, and this is probably the most familiar of the species. These cells have been compressed, but the body is usually spindle-shaped. Although two flagella arise in a pocket within the cell only one emerges. The body can squirm, and the cell has many chloroplasts. At the anterior of the body a thin channel (flagellar canal) leads to the flagellar pocket, and alongside this is a contractile vacuole. A red eyespot or stigma is associated with the bottom of the flagellar canal. This image shows the nucleus (central). Differential interference contrast.

Euglena gracilis. Cell observed in freshwater habitats in the vicinity of Broome, Western Australia in September 2003. This image was taken using differential interference contrast optics.   This work was supported by the Australian Biological Resources Study.

Whole cell, the dark eyespot is near the front and adjacent to it is the flagellar pocket / reservoir / contractile vacuole region. the nucleus is the clear structure near the posterior of the cell. The positions of about 6 large plastids can be worked out. Animations by Rosemary Arbur of flagellar beat patterns are available here.
