WebThe effects of cilium length on the dynamics of cilia motion were investigated by high-speed video microscopy of uniciliated mutants of the swimming alga, Chlamydomonas reinhardtii. Cells with short cilia were obtained by deciliating cells via pH shock and allowing cilia to reassemble for limited times. The frequency of cilia beating was estimated from the … WebAn axoneme is the microtubule cytoskeleton of the cilium, consisting of a ring of nine doublet microtubules surrounding a central pair (9+2). ...
