Abstract

SUMMARY

Myxamoebae of and the stages of their development of flagella during transformation into biflagellate swarm cells were examined with the electron microscope. Fixation was with glutaraldehyde osmium. The flagellation process was similar to that reported in other systems, involving budding of the basal body into a primary flagellar vesicle which then forms the flagella sheath. Two basal bodies are present in the myxamoeba prior to flagellum development; other morphological features of myxamoebae and swarm cells, including systems of microtubules, are described. Mitochondria of both stages contain a dense core, flagella exhibit the typical ‘9 plus 2’ arrangement, and the doublet fibrils of the axoneme become singlets near the rounded distal end of the flagellum.
