Symbiosis occurs when two different species benefit from living and working together. When one organism actually lives inside the other it's called endosymbiosis. The endosymbiotic theory describes how a large host cell and ingested bacteria could easily become dependent on one another for survival, resulting in a permanent relationship. Over millions of years of evolution, mitochondria and chloroplasts have become more specialized and today they cannot live outside the cell.
The term used for an organism living in or on another depends on  the nature of the relationship.    - If the relationship is mutually beneficial (mutalism) then the  â¦ organism can be called a symbiont.   - If the relationship does not benefit the host, the organism can  be called a parasite.   Parasites can be endoparasites, which live inside the host, or  ectoparasites, which live on the host.    Some biologists use the term symbiont for any organism in a close  interaction with another.
