Description
One might properly ask what "primitive motile systems" are and why they are of interest. If it had not been for the invention of the microscope, the study of motility might well have remained restricted to the study of muscular contraction. However, early microscopists saw and described the marvelous diversity of movements among protozoans and other lower organisms, and it was not long before hypotheses were advanced to explain the movements of these creatures. Each succeeding generation of biologists has seen the gliding of cells, protoplasmic streaming, pseudopodial movement, the beating of cilia and flagella, mitotic movements of chromosomes, saltatory motions of various cytoplasmic particles, contractions of myonemes and other structures, and various other nonmuscular movements. Despite two centuries or more of study with ever-improving methods of study, however, the basic problem as to the mechanism of these various movements has remained unsolved.
