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.
Definition. A symbiont is an organism that is very closely associated with another, usually larger, organism. This larger organism is called a host. A symbiont can live on, in, or sometimes very near its host.There are two categories of symbionts: 1  An ectosymbiont lives outside of its host's cells.eutralism is when a symbiont and a host have no effect on each other.
