An electron micrograph of a cross section of a flagellum from the unicellular alga Chlamydomonas (Yellow strain) showing the characteristic 9-fold symmetry. This section, close to the basal body does ...

A high resolution image of the surface of Coleps hirtus. Alveoli have longitudinal margins along the ciliary rows as well as lateral margins spaced at intervals of one or two basal bodies along the ro...

A grazing section through the dorsal surface of Euplotes showing cross sections of cilia in four of the sparsely ciliated kineties . A layer of mitochondria underlies the pellicle. A replication band ...

Cross section of a cilium showing the 9 + 2 axoneme. Two dynein arms, inner and outer, of heterogeneous appearance arise from the complete microtubule of each doublet. Spokes extend from the doublets ...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...

High resolution image of longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Adjacent digestive vacuoles and cortical cytoplasm evide...

High resolution overview of Coleps hirtus cell seen in this median transverse section. This barrel-shaped cell has a few rows of cilia and the cell is covered with calcified polysaccharide platelets t...

A high resolution image of the detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by ...

High resolution image of the detail of the three fibers supporting a basal body. A striated kinetodesmal fiber extends anteriorly from the basal body, a postciliary microtubular ribbon extends posteri...

High resolution image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the n...
