[The ecological-morphological characteristics of the growth and distribution of cultures of single-cell organisms in a gravitational field].

The paper analyses and summarizes the experimental results obtained by the authors and data accumulated in the literature during recent years in order to reveal the general regularities of the growth, distribution and behavioral parameters of the cells under conditions of reduced gravity ranged from 10(-5) to 5 g. It is indicated that an intensity of gravity effect on these parameters of unicellular organisms depends greatly on the environments, types of cells and their metabolic levels. The effects of changed gravity at the cellular level are the result of shifting the primary physiological characteristics and physicochemical parameters of the culture and cell environments as an integrated biological system.
