The definition of symbiosis was a matter of debate for 130 years. [7] In 1877, Albert Bernhard Frank used the term symbiosis to describe the mutualistic relationship in lichens. [8] [9] In 1878, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms".
The symbiosis of the Chlorella–Hydra first described the symbiosome. The coral Zoanthus robustus has been used as a model organism to study the symbiosis with its microsymbiont algal species of Symbiodinium, with a focus on the symbiosome and its membranes. Methods for isolating the symbiosome membranes have been looked for – the symbiont ...
The symbiosis is rendered more complex than just simple mutualism, both by the physiological discrepancy between language as an overall condition and the nature of individual ideas conveyed through language, as well as by the ecological difference between vertically and horizontally transmitted memes.
Symbiosis includes three types of interactions—mutualism, commensalism, and parasitism—of which only mutualism can sometimes qualify as cooperation. Mutualism involves a close, mutually beneficial interaction between two different biological species, whereas "cooperation" is a more general term that can involve looser interactions and can ...
There are two major modes of transmission for symbiotic bacteria. The first is horizontal transmission in which microbes are acquired from the environment and either the environment or the host population serves as the inoculum for the symbiosis. [7] An example of horizontal transmission is the deep sea tube worm and its symbiont. [7]
The concept of a consortium was first introduced by Johannes Reinke in 1872, [4] [5] and in 1877 the term symbiosis was introduced and later expanded on. Evidence for symbiosis between microbes strongly suggests it to have been a necessary precursor of the evolution of land plants and for their transition from algal communities in the sea to ...
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Symbiosis is any type of a close and long-term biological interaction between two different biological organisms: it can be mutualistic, commensalistic, or parasitic. The terms are also used in relation to business relationships.
