维持一定的跨质膜电势,关乎到细胞内外物质交换的基本代谢能否顺利进行,因此是所有细胞生存的前提。这是生物的单细胞祖先发展出的有效生存手段,当进化到多细胞生物体后却遇到麻烦。多细胞生物为细胞营群居生活,在物理导体的静电荷分布规律的支配下,个体细胞所携外正内负的净电荷有向细胞集团边缘汇集的趋势,导致多数细胞失去本身所携净电荷,不能维持正常跨膜电势,从而逐渐失去活力。这可能就是多细胞生物衰老的根本原因。衰老是生物体在发育中随细胞数量增多不可避免的自然发生的效应。有证据显示以上描述的电荷分布变化过程的假说是真实存在。植物体中细胞所携电荷的汇集,以及随之发生的带电离子从高浓度区向低浓度区的扩散流失,可导致产生有趣的植物生电的现象,例如大树发电。对植物电压、电的极性、高密度电荷位点分布的测结果与此假说理论完全吻合。
Maintain a certain potential across the plasma membrane, related to the basic metabolism of the exchange of material inside and outside the cell can proceed smoothly, and therefore is a prerequisite for the survival of all cells. This is an effective means of living developed by a single, unicellular ancestor of organisms that, after evolving into a multicellular organism, has trouble. The multicellular organisms are living in cell camps. Under the regulation of the static charge distribution of physical conductors, the net positive and negative net charges carried by individual cells tend to converge to the edge of cell groups, resulting in the loss of most of the cells’ net charges , Can not maintain the normal transmembrane potential, which gradually lost its vitality. This may be the root cause of the aging of multicellular organisms. Aging is an inevitable natural occurrence of an organism as it grows with an increasing number of cells. There is evidence that the hypothesis of the charge distribution change described above is real. Accumulation of charges carried by cells in plants and consequent diffusion of charged ions from regions of high concentration to regions of low concentration can lead to interesting phenomena of plant electrification such as tree power generation. The results of plant voltage, electrical polarity and high-density charge site distribution are completely consistent with this hypothesis theory.
