Living Lilium pollen tube labeled with dichloro-flourescein diacetate to mark the vacuole and imaged using laser scanning focal microscopy. Shown is a central 1.0 micron thick x-y slice.The growing ...

Leishmania mexicana amastigotes in their parasitophorous vacuole in a mouse macrophage. Murine macrophages (cell line J774) were infected in vitro with Leishmania mexicana stationary phase promastigot...

Cytosolic pressure may be one force used to expel the undigested contents from spent vacuoles, however, tubulation and retrieval of the spent vacuole membrane will ultimately eliminate all of the vacu...

Grazing section through an accumulation of uncoated cupulas in the process of attachment to and fusion with a food vacuole membrane. The small round pores apparently represent early stages of fusion o...

A live amoeba treated with the membrane-binding vital dye FM4-64 which stains the plasma membrane, contractile vacuole and other organelles. Large membrane-bounded organelles are excluded from the bro...

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...

Grazing section through an accumulation of uncoated cupulas in the process of attachment to and fusion with a food vacuole membrane. The small round pores apparently represent early stages of fusion o...

Transmission electron micrograph of an unbudded yeast cell treaated with 60µM sertraline. The vacuolar contents are more electron-lucent, and vacuolar membrane is more discernible. A single lipid dro...

Euplotes sp. (eurystomus ?) is a hypotrich. This ciliate has a few rows of dorsal cilia as well as specialized clumps of cilia called cirri on its ventral side and a complex of membranelles involved i...

Cross section through a radial arm of the contractile vacuole complex. The collecting canal occupies the center of the arm whose membrane is supported by the radial microtubular ribbon which has now d...
