Lichens symbiotic associations between an alga or cyanobacterium ( the photobiont ) and a fungus ( the mycobiont ) 地衣:藍(lán)、綠藻類(共生光合生物)和真菌(地衣共生菌)所形成的共生復(fù)合體。
This has led to the theory ( endosymbiont theory ) that eukaryotes arose as a result of symbiotic associations between prokaryotes 這就形成了真核生物中某些細(xì)胞器來自于共生的原核生物的理論(內(nèi)共生理論) 。
Some form symbiotic associations with algae or cyanobacteria to form lichens , while others form extremely important mycorrhizae with the roots of many plants , including most forest trees 真菌是土壤和淡水中主要的分解者,一些與藻類或藍(lán)細(xì)菌共生形成地衣,還有一些真菌與許多植物包括大多數(shù)林木的根形成大量的菌根。
Mineralization conditions are multiple , abnormity of geochemical exp1oration related with the symbiotic association of the elements in the main mineralization is also multiple . the association of different elements appears some optimum proportion under the mineralization conditions , known as ration composite anomaly 成礦條件是多元的,與主成礦元素共生組合具有某種對應(yīng)關(guān)系的化探異常也是多元的,其元素組合在成礦條件下呈某種最佳比例關(guān)系,稱為定量組合異常。
