| Outline of Final Research Achievements |
Symbiont-bearing planktonic protozoa are widely distributed in the euphotic zone of the oligotrophic ocean. To examine the potential contribution of the symbiotic algae to the host protozoa, we developed a new method for measuring the chlorophyll a content and photosynthetic activity of live symbiotic algae within individual cells of host protozoa. By using the new method, we found that the chlorophyll a content and photosynthetic activity of the symbiotic algae varied greatly over the life cycle (e.g., growth and gametogenesis phases) of their host.
