from ‘greek’ –>
συμβίωσις
“living together”
from σύν (“together”) + βίωσις (“living”)
.
(‘symbosis’ ia a ‘close’ (+ often ‘long-term’) interaction between 2 different ‘biological species’)
.
(in ‘1877’, ‘albert bernhard frank’ used the word symbiosis (which previously had been used to depict people living together in community) to describe the ‘mutualistic relationship’ in ‘lichens’)
(in ‘1879’, the german mycologist ‘heinrich anton de bary’ defined it as “the living together of ‘unlike organisms'”)
.
*the definition of ‘symbiosis’ has varied among scientists*
.
(some believe ‘symbiosis’ should only refer to ‘persistent mutualisms’…)
.
(…while others believe it should apply to any type of ‘persistent biological interaction’)
.
(in other words…)
(‘mutualistic’ / ‘commensalistic’ / ‘parasitic’)
.
(after 130 years of debate, current (‘biology’ / ‘ecology’) textbooks now use the latter “de bary definition”…)
.
(…or an even broader definition where ‘symbiosis’ means all ‘species interactions’, with the ‘restrictive definition’ (in which ‘symbiosis’ only refers to ‘mutualism’) no longer used)
.
(some ‘symbiotic relationships’ are ‘obligate’)
(meaning that both ‘symbionts’ entirely depend on each other for ‘survival’)
(for example, many ‘lichens’ consist of ‘fungal’ + ‘photosynthetic’ symbionts that cannot live ‘on their own’)
(in other words they ‘could use a little help’)
(“the golden rule” + “guiding principle’ on a ‘cellular level’)
(muc like christians extolling of the vritues of helping those ‘in need’)
“yes indeed!”
(others are ‘facultative’ (aka ‘optional’))
(meaning they ‘can’, but ‘do not have to’ live with the other ‘organism’)
(‘symbiotic relationships’ include those ‘associations’ in which…)
1 ‘organism’ lives on another…
*ectosymbiosis*
(such as ‘mistletoe’)
(…or where 1 partner lives inside the other)
*endosymbiosis*
(such as ‘lactobacilli’ and other ‘bacteria’ in ‘humans’)
(or ‘symbiodinium‘ in ‘corals’)
.
(‘symbiosis’ is also classified by ‘physical attachment’ of the ‘organisms’….)
.
(‘symbiosis’ in which the ‘organisms’ have ‘bodily union’ is called ‘conjunctive symbiosis’)
.
(‘symbiosis’ in which they are not ‘in union’ is called ‘disjunctive symbiosis’)
