Textbooks now use the latter "de Bary" definition or an even broader definition (i.e. symbiosis = all species interactions).
Some symbiotic relationships are obligate, meaning that both symbionts entirely depend on
each other for survival cannot live on their own. Others are facultative, meaning that they can,
but do not have to live with the other organism.
Symbiotic relationships include those associations in which one organism lives on another
(ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans.
Parasites, for example, have a symbiotic relationship with their hosts, but only the parasite benefits.

Symbiosis is close and often long-terminteractions between different biological species. A relationship of mutual benefit or dependence is symbiosis.

Symbiosis is a close, prolonged association between two (or more) organisms of different species that may, but does not necessarily, benefit each member. The specific biological interactions of symbiosis can be subdivided in three: * Mutualism, where both organisms benefit. * Commensalism, where only one of them benefits, but the other is not affected. * Parasitism, where one benefits and the other organism is harmed.
Symbiosis interaction between two or more different biological species. Both mitochondria and chloroplasts can arise only from preexisting mitochondria and chloroplasts. Therefore this notion is not factual.
A symbiotic relationship is a close and often long-term interaction between different biological species.
This sort of relationship is called a "symbiosis."
