"What interested me about the paramecium is not only that it was one of the first microorganisms discovered," Lightman says, "but the mechanisms of its locomotion, the little cilia that wave back ...

A paramecium moves by the beating of its cilia; an amoeba, by the streaming of its cytoplasm; a muscle, by its over-all contraction. All these processes appear to share an underlying molecular unity ...

Anatomical and chemical views of the cell have now converged to show that it is not a droplet of protoplasm but a highly organized molecular factory A paramecium moves by the beating of its cilia ...

Now that is a paramecium. It may look like a simple animal ... The cell swims around powered by a cohort of cilia, tiny hairs embedded in the cell membrane. If it bumps into something, the ...
