An image of the contractile vacuole in diastole (filling phase). Decorated spongiome surrounds the CV. The macronucleus, micronucleus, cytopharynx, and basal bodies of perioral membranelle are include...

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...

This group represents a serial series of sections. At the level of this section, the macronucleus and micronucleus are present. In the buccal cavity a row of paroral cilia is seen to separate the bucc...

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 ...

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...

Daughter micronucleus in anaphase of a dividing cell of Didinium nasutum. The chromosomes are compacted into one large heterochromatic body. Remnants of the mitotic division spindle remain inside the ...

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...

Like other ciliates two types of nuclei are present. A germinative micronucleus and a RNA-producing macronucleus. Both have nuclear envelopes with pores and both have ribosomes attached to their outer...

High resolution image of the interphase micronucleus with only a small amount of b-tubulin in its matrix or on its nuclear envelope. Segments of microtubules are scattered in the cytosol. Immunogold l...
