Jenna Sutela. Holobiont
»Holobiont« is a Greek composite: »hólos« - everything, overall, »bios« - live and »óntos« -beings. They are considered as multipartite ecological entities as it is a merge of several organisms of different species to a super organism. The word goes back to the US biologist Lynn Margulis, that showed that more complex cells, for example human cells have their origin in the fusion of simpler organisms.
