The Cytology of Prochloron

  • Hewson Swift


Cytological observations made on Prochloron cells from a variety of didemnid hosts present a consistent picture. Characteristic differences occur between cells from different sources (Figures 10, 12–14), but obvious similarities indicate that these organisms form a coherent and probably closely related group. Prochlorophytes are clearly prokaryotes. Nuclei and mitochondria are absent. Photosynthetic membranes are free in the cell and are not packaged into chloropiasts. Various inclusions, DNA filaments, protein crystalloids, pigment and storage granules are usually not membrane-limited. The only other true membrane systems present are the cell-limiting plasmalemma and membranes surrounding vacuole-like regions of low optical density.
