Figure 1. Anatomy of a Stentor coeruleus cell
Brightfield images of both an extended cell (left) and a contracted cell (right) highlighting a few key features. The oral cilia are at the anterior and constantly beat to create a vortex to capture food particles in the buccal cavity. The contractile vacuole can be seen beneath the cell membrane and is also associated with scars in the membrane called contractile vacuole pores. The cell’s macronucleus is stretched along its length and packaged into distinct nodes, giving it the appearance of ‘beads on a string’. The cortical stripes are also visible; the clear stripes represent microtubule bundles known as Km fibers and the blue/green stripes contain dense fields of pigment granules. Asymmetric spacing of the rows results in a point at which the wide stripes meet the narrow stripes and is called the locus of stripe contrast. The posterior of the cell is defined by an anchoring structure known as the holdfast.
