绿色植物都能自已制造有机养料,在制造有机养料的过程中,有的植物表现得很显著。象这一类的植物用来做光合作用实验是最好的,凤仙花就是其中的一种。凤仙花这种植物很普遍,可能在各个学校都有栽培。利用这种植物做光合作用实验,我进行了几次,效果都很好。我做的方法是这样的,将凤仙花栽在小花盆里(这样便利搬移),当叶子长到适当宽阔时,就可进行实验。进行实验前,先将它放在黑暗的地方,一昼夜后取出, Green plants can produce their own organic food, in the manufacture of organic food in the process, some plants showed remarkable. Plants like this one are best used for photosynthesis experiments, and Impatiens are one of them. Impatiens This plant is very common and may have been cultivated in all schools. Using this plant for photosynthesis experiments, I conducted several times, the effect is very good. The way I did it was to plant the impatiens in small pots (this is a handy move), and experiments can be carried out when the leaves grow to the appropriate width. Before the experiment, first place it in the dark place, remove it after a day and night,
