Effects of Weightlessness on the Nutrition and Growth of Pelomyxa carolinensis (P-1035A)
Species Studied
Pelomyxa carolinensis
(Amoeba)
Objectives:The study's objectives were to survey the fine structure and distribution of mitochondria, nuclei, nucleoli, Golgi apparatus, and endoplasmic reticulum for changes that may have been induced by weightlessness, and to determine if there were normal growth patterns or normal progression of food vacuole digestion in amoebae subjected to a weightless environment.
