Popis: 1. 1. Soluble extracellular products of symbiotic algae (zoochlorellae) from Paramecium bursaria, Spongilla sp. and a mutant Chlorohydra viridissima were identified after photosynthesis in the presence of NaHC 14 O 3 and compared to the products of ten strains of free-living algae. 2. 2. All of the symbiotic strains liberated soluble maltose principally or glucose to the extent of 5·4–86·7 per cent of their total photosynthate. All of the free-living strains liberated 0·4–7·6 per cent of their total photosynthate principally as glycolic acid. 3. 3. Liberation of soluble carbohydrate by symbiotic algae from fresh-water representatives of three animal phyla and by lichen algae is viewed as an adaptation to symbiosis.
