生命的激动者为什么一粒种子,种在土地上,就会生根、发芽,开花结籽,而砂礫、岩石却没有这种现象?很容易理解,生物与非生物的根本区别,在于生物是有生命的有机体,它能与周围环境不断地进行着物质交换——新陈代谢。绿色植物的新陈代谢能够在阳光底下利用水和二氧化碳,以及无机营养物来制造有机物质,如碳水化合物、脂肪、蛋白质等;然后在体内又被“消化”分解,并释放出能量,供给本身生长、发育之用。由此看来,植物的一生,其实是包括着一系列的化学反应过程。但是,这些化学反应要是在植物体外进行人工试验,则需要在高温、高压、强酸、强碱等作用条件下才能 Why do the exciters of life plant seeds on the ground, they will take root, germinate, and flower seeds, whereas gravel and rocks have no such phenomenon? It is easy to understand that the fundamental difference between living and non-living is that An organism that lives, it can continuously exchange material with the surrounding environment - metabolism. The metabolism of green plants can use water and carbon dioxide under the sun, as well as inorganic nutrients to produce organic substances, such as carbohydrates, fats, proteins, etc.; then they are “digested” in the body to decompose and release energy, and the supply itself grows, The use of development. It seems that the life of a plant actually involves a series of chemical reactions. However, if these chemical reactions are artificially tested outside the plant, they need to be under conditions of high temperature, high pressure, strong acid, and strong alkali.
