EXPERIMENT INFORMATION

Effects of Weightlessness on the Nutrition and Growth of Pelomyxa carolinensis (P-1035A)
Principal Investigator
Research Area:
Cell and molecular biology
Species Studied
Scientific Name: Pelomyxa carolinensis Species: Amoeba

Description
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.
