The endosymbiosis between Paramecium bursaria and Chlorella spp. is mutualistic. Symbiotic algae localize beneath the host Paramecium cell cortex compete for their attachment sites with preexisting organelle trichocysts. To examine the relationship between P. bursaria trichocysts and their symbiotic algae, algae-bearing or alga-free P. bursaria were starved for several days and the changes in the number of Chlorella sp. and presence or absence of trichocysts were evaluated. We conducted an indirect immunofluorescence microscopy with
