Summary
Features of the cytology and ultrastructure of the life cycle ofAcetabularia mediterranea from events leading to the division of the primary nucleus to cysts formation are described. In agreement with the work ofBoloukhère (1969, 1970, 1972) the loss of the ramiform primary nucleolus, and striking changes in the rhizoid chloroplasts are observed. The development of the secondary nuclei, and their associated basophilic aggregates, the presence of cytoplasmic microtubules, and the process of cytoplasmic cleavage are described and discussed. Golgi bodies appear to be involved in cell wall synthesis.
