| symbiotic algae | <plant biology> Algae (often Chlorella spp) that live intracellularly in animal cells (e.g. Endoderm of Hydra viridis). The relationship is complex, because lysosomes do not fuse with the vacuoles containing the algae and the growth rates of both cells are regulated to maintain the symbiosis. There is considerable strain specificity. The term is imprecise, since there are many other symbiotic algae (as in lichens) where the relationship is different. (19 Jan 1998) |
| symbiotic fermentation phenomenon | "two organisms, neither of which alone produces gas fermentation in certain carbohydrates, may do so when living in symbiosis or when artificially mixed" (Castellani). (05 Mar 2000) |
