title: [Effect of symbiotic algae on the photoaccumulation capacity of cells of the ciliate Paramecium bursaria].
abstract: The character of the effect produced by symbiotic algae on photodependent behavior of their host ciliates, Paramecium bursaria, was determined. Partially alga-freed paramecia showed a reliable increase in the rates of photoaccumulation. The photoaccumulation rate gradually decreased with a further decrease in the number of zoochlorellae. Once the chlorophyll content fell down to 20-25 mu/l, the ciliates lost their capacity for photoaccululation. A mathematical model of photoaccumulation has been constructed.
