A partially filled contractile vacuole is connected to two regions of spongiome tubules. The extra CV membrane is acquired from these spongiomes. Presumably some of these spongiome tubules are decorat...

Transmission electron micrograph of a yeast cell exposed to 60µM antidepressant sertraline. This high-magnification zoom of CIL 39708 shows a double-membrane autophagosome. Encapsulated inside the a...

Figures 264 (upper) and 265 (lower) from Chapter 8 (Lysosomes) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Lysosomes apparent in thin sections from liver tissue of hamster treated with phenobarbito...

Transmission electron micrograph of an unbudded yeast cell treated with 60µM sertraline. Two autophagosomes containing membranous material are visible. Higher magnification images of ultrastructural...

Figure 275 from Chapter 8 (Lysosomes) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Lysosomes of cells engaged in heterophagy, like the Sertoli cells from the testis of the chinchilla shown here, are...

Higher magnification view of the spongiome of the Contractile Vacuole Complex. The spongiome is composed of a three dimensional array of tubules that are continuous with the CV membrane. Many tubules ...

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 ...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; micronucleus; contr...

The decorated spongiome of the CVC is composed of 50nm tubules that have a pattern of helically wound subunits attached to their cytosolic surfaces. These tubules can be up to one micrometer or more i...
