A confocal micrograph of stained and autofluorescent cells of xylem in the stem of buttercup (Ranunculus), showing xylem vessels whose walls are studded with pits that allow passage of water from one ...

A high resolution 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 (centrifi...

Some tubules near a contractile vacuole which appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type proton pumps (V-ATPases...

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...

High resolution image of the contractile vacuole and the spongiome decorated tubules showing V-type proton pumps extending from the cytosolic side of the tubules; also detail of the micronucleus. TEM ...

A rare micrograph of the contractile vacuole and intact contractile vacuole pore membrane of Euplotes. Close examination at high magnification reveals the organization of microtubules lining the pore ...

An image of the contractile vacuole and the spongiome decorated tubules showing V-type proton pumps extending from the cytosolic side of the tubules; also detail of the micronucleus. TEM taken on 6/10...

A high resolution of some tubules near a contractile vacuole that appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type pro...

An 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 shows the pore ...
