High resolution image of one of several contractile vacuole pores of the proter of a dividing cell. This is presumably at an early stage of development as division is not yet complete. This section sh...

The contractile vacuole pore is encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell where they provide st...

A high magnification view of the tubulated CV membrane attached to ampullae 2, 3, 4 and 5 of the CVC. The tubules lie against the ribbon of microtubules as well as form a large mat lying inward (centr...
