Single microtubules extend into the cytoplasm from the tips of the cytoproct ridge. These are thought to come to lie along the surface of the approaching DV-IV and to pull the ridge down against the D...

Acid phosphatase is present in tubules retrieved from late DV-III. The tubules and rounded expansions arising as a result of late DV-III membrane retrieval contain an electron-opaque reaction product ...

The proximal end of the basal body is sometimes the origin of other single microtubules or bundles of microtubules that extend deeper into the cell’s endoplasm. These guide trichocysts, tip first, t...

Like other cells Paramecium has peroxisomes. These organelles are usually smaller than mitochondria and have a granular appearance and contain a few tubular-like inclusions. These tubules have not bee...
