基于酸碱指示剂石蕊的变色原理,以实验的方法直观表现了植物体内化学平衡移动的存在,探讨了植物花朵颜色变化及恢复与植物细胞液泡中pH的关系。
Based on the discoloration principle of the acid-base indicator litmus, the existence of chemical equilibrium movement in plants was visually demonstrated by experimental methods. The relationship between the color change of plant flowers and the pH value in plant vacuoles was also discussed.
