学校校园内种有大量的红花酢浆草,每到晚上,红花酢浆草的掌状复叶会合拢,而天亮了叶片又重新张开,是什么因素、什么机制导致了叶片的按时开闭呢?针对这些问题,我们决定展开研究。在实验室研究时,我们发现一个奇怪的现象:放在学校实验室的小隔间(很暗)内的一盆红花酢浆草,在几乎没有阳光照射的上午,叶片依然是张开的。植物叶片在晚上闭合应该是受光照影响的缘故,而实验室的暗室就像黑夜,为什么叶片也
There are a large number of saffron shamrocks planted on the school campus. At night, the palmate compound leaves of the shamrocks will be closed, and the leaves will be reopened at dawn. What are the factors and what mechanism leads to the leaves on time? For these issues, we decided to start research. During laboratory research, we found a strange phenomenon: a pot of red shamrock in a small (very dark) cubicle of a school laboratory. In the morning with barely sunlight, the leaves are still open. . The closing of plant leaves at night should be due to the influence of light, while the dark room of the laboratory is like night, why the leaves are also
