Notes
The digestion of food in the ciliate Nassula aurea Ehrenberg is studied using transmission electron microscopy. During the food uptake numerous vesicles fuse with the food vacuole and secrete a flocculent material into it. This process causes the degradation of the cell walls of the food, the blue-green alga Phormidium autumnale. The digestion of the algal cytoplasm starts at a later time. After desintegration of the food, numerous longish folds become visible around the periphery of the food vacuole. These folds might facilitate the resorption of the nutrients. In starved cells many vacuoles filled with electron dense globules are encountered. The fate of the globules remains obscure because these cells will die very soon. Several anomalies in the mitochondrial ultrastructure are related to starvation.
