真菌与绿色植物的一个重要区别,是它不能进行光合作用,而是依靠从其生长的基物中,吸取现成的营养成份,转化后构成自身的组成份和生长繁殖过程中所需要的能量。食用真菌在自然界中生长的情况下,是从其生长的树木或土壤、枯枝烂叶中,吸收现成的有机营养成分。在人工培养的条件下 An important difference between fungi and greenery is that it can not carry out photosynthesis. Instead, it relies on the substrate from which it is grown, absorbs ready-made nutrients, converts itself into components of the composition and the energy required for growth and reproduction. In the case of edible fungi that grow in nature, they readily absorb readily available organic nutrients from their growing trees or soils, litter and rotting leaves.
