世界上最早的生命是在逐渐冷却的原始海洋里,由蛋白质和其它化合物产生出来的。植物也是首先在水里发生,而后逐渐进化为陆生植物。水分乃是植物的一个重要的先天环境条件。无数事实证明,植物的一切正常生命活动都必须在一定的细胞水分状况下才能进行,在一定范围内,细胞代谢活动的强弱与其含水量成正相关,可见水对生命 The earliest life in the world was created by proteins and other compounds in a gradually cooling pristine sea. Plants are also the first in the water, and then gradually evolved into terrestrial plants. Moisture is an important congenital environment for plants. Numerous facts have proved that all the normal life activities of plants must be carried out under certain cellular and water conditions. In a certain range, the strength of cellular metabolic activity is positively correlated with its water content.
