Contractile vacuole in the opisthe of a dividing cell. This is presumably the mature CV of the original “mother” cell. Spongiome tubules form large regions of additional membrane on two sides of t...

This group represents a serial series of sections. At the level of this section, the macronucleus and micronucleus are present. The buccal cavity with cilia and the spongiome of CV, membranelles of pe...

A high resolution image of a part of the CVC complex with some filled ampullae present. Masses of collapsed CV membrane are associated with the 11 microtubular ribbons. Ribbon 9 is curving away from t...

A contractile vacuole in systole. The CV has collapsed into vesicles and tubules. Three CV pores can be seen where the CV meets the pellicle. Smooth membrane cisterna surrounds some cytoplasm, possibl...

High resolution image of the contractile vacuole in diastole (filling phase). Decorated spongiome surrounds the CV. The macronucleus, micronucleus, cytopharynx, and basal bodies of perioral membranell...

High resolution micrograph of the contractile vacuole of Coleps hirtus. The filled CV is continuous with tubules of the smooth spongiome. The tubular nature of mitochondrial cristae is particularly ev...

DVD quality video of the Contractile Vacuole Complex of Paramecium multimicronucleatum. In vivo CVC filling/expulsion cycles. A CV in a compressed cell is observed in side view undergoing cycles of fi...

Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. Measuring membrane tension of the in vitro CV. To measure the build up of tension by the CV membrane an in vitro CV surrounde...

The contractile vacuole of Coleps hirtus. The filled CV is continuous with tubules of the smooth spongiome. The tubular nature of mitochondrial cristae is particularly evident in this micrograph. Stan...

In Euplotes a replication band of the macronucleus has larger heterochromatin masses on one side of the band after DNA replication has occurred. The replication band moves in the direction of lighter...
