We all of us live in symbiosiswith the bacteria in our digestive tracts, don't we?
Two life-forms live together, and each one helps the other--that's all symbiosis is.
Symbiosis is probably the best word for it," Dal had replied.
Symbiosis and commensalism must be distinguished from parasitism, which indicates that all the advantage is on the side of the parasite, and nothing but loss on the side of the host.
It is convenient to restrict the term symbiosis to complementary partnerships such as exist between algoid and fungoid elements in lichens, or between unicellular algæ and Radiolarians,[45] or between bacteria and higher plants.
At a later stage we shall have an opportunity of discussing symbiosis and allied conditions.
In the first place, these matters are simplified by the fact that there is very little fixation indeed by bacteria in the soil apart from symbiosis with higher plants.
That under the conditions of symbiosis the plant is enabled to fix the free nitrogen of the atmosphere by its leaves; "2.
The example of bacteriological symbiosis with which we are concerned here is that partnership between bacteria and some of the higher plants (Leguminosæ) for the purpose of fixing nitrogen in the plant and in the surrounding soil.
The distinction between symbiosis and commensalism cannot be rigid, but between these conditions which are advantageous to the partners and parasitism, there is an obvious and radical difference.
Symbiosis is found among the protista, being very wide-spread among the radiolaria.
In general, however symbiosis is rarer in the metazoa than in the metaphyta.
From parasitism we must entirely distinguish that intimate life-union of two different organisms which we called symbiosis or mutualism.
Japan had for centuries had a middle class (the merchants) that had entered into a symbiosis with the feudal lords.
The result of the three centuries that had passed was a symbiosis between the urban aristocrats and the country-people.
This interesting case of symbiosis is equalled by yet another case.
We have here a very interesting case of symbiosis as mentioned above.
The concepts parasitism, predatism, and symbiosis have all been used with various shades of meaning by different authors.
The symbiosis between the wood-feeding roach, Cryptocercus punctulatus Scudder, and its intestinal flagellates.
The wood-feeding roach Cryptocercus, its protozoa, and the symbiosis between protozoa and roach.
Symbiosis with burrowing animals is another solution to the problem of existence in the desert; in fact, symbiosis is a mode of life adopted by nearly half of the desert cockroaches about which we have any information.
Parasitism= is the state of symbiosis in which one of the members feeds upon the other during the whole of either the immature or mature feeding stage; the host is harmed in some way and may be killed.
Mutualism= issymbiosis in which both members benefit by the association.
In symbiosis the bacteria probably undergo changes by which they become adapted to the environment, and in parasitism the environment becomes adapted to them.
It is evident that symbiosis is the most favorable condition for the existence of the parasite, and an injurious action exerted by the parasite on the host unfavorable.
He suggested that their symbiosis might be an essential condition, and was obliged finally to leave it an open question whether the cells of the tubercles or the bacteroids were the active agents in nitrogen assimilation.
A truce is sometimes called in the struggle, and host and parasite are content to live together in a mutually advantageous symbiosis or commensalism.
In the study of symbiosis among animals, it is significant to note the presence of structural adaptations in one or both species.
In the taming and domestication of animals by man the effects of symbiosis are manifest.
Are changes resulting from human symbiosis changes (a) of structure, or (b) of function?
There is scarce a forest or a bushland where examples of these forms of symbiosis are lacking; if, for instance, we investigate the tropical rain-forest we are certain to find in it all conceivable kinds of symbiosis.
The analysis of a plant-community usually reveals one or more of the kinds of symbiosis as illustrated by parasites, saprophytes, epiphytes, and the like.
What are the likenesses and the differences between social symbiosis in human and in ant society?
The continuation of thesymbiosis is unbroken and guaranteed.
A symbiote--and Dis was the world where symbiosis and parasitism had become more advanced and complex than on any other planet.
He knows things about symbiosis and mutualism that would get him a job as a lecturer in any university on Earth.
Symbiosis is observable in many plants other than the leguminosæ, and it is certain that many of our big forest trees depend for their nourishment upon fungi which grow upon their roots.
Lichens are a living symbiosis of algæ and fungi: the pagurus allows the actiniæ to settle on his dwelling, where they attract his prey and in return are housed and conveyed from place to place.
The close symbiosis between "Azotobacter" and similar nitrogen-absorbing bacteria and many species of algae in sea water at least.
G--Metabolism simple, growth processes involving oxidation of alcohol or fixation of free N (latter in symbiosis with green plants).
Since then numerous other cases ofsymbiosis have been demonstrated.
Then, as spores of mycorrhizal fungi begin falling on the bed and their hyphae become established, scattered trees begin to develop the necessary symbiosis and their growth takes off.
Certain types of fungi are able to form a symbiosis with specific plant species.
But the symbiosis of the Xanthellae and Radiolaria is not as in the lichens a phenomenon essential for their development, but has more or less the character of an accidental association.
Recently the vegetative physiology of the Radiolaria has been much advanced by the recognition of the symbiosiswith the Xanthellae (s 205, L.
This symbiosis is not necessary, however, for the existence of the Radiolaria; for in many species the number of Xanthellae is very variable and in many others they are entirely wanting.
Xanthellae or Philozoa, the unicellular Algae, with which they live in symbiosis (s 205).
In any case their symbiosis is to a large extent accidental, by no means as necessary as in the case of the Lichens.
Naturally the xanthellae or yellow cells (ss 76, 90), which as independent algae live in symbiosis with many Radiolaria, must be excluded.
The scion differs from a cutting, however, in having no roots of its own: it is parasitic upon, or rather is in symbiosis with the stock, the root and tissues of which intervene between it and the soil.
The symbiosis between all life-forms on our planet is the result of that knowledge.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "symbiosis" in a variety of sentences. We hope that you will now be able to make sentences using this word.
