很少有人去思考,植物的枝干为什么往上长,根却往地下扎。我们知道,人很容易分辨方位,因为人有一套非常复杂的感觉系统,那么,植物怎么分清方向呢?植物也有感觉器官吗?目前,科学家希望借助空间科学,揭示植物的生长奥秘。 Few people think about why the branches of plants grow upwards, but roots go underground. We know that people can easily tell the location, because people have a very complex sensory system, then, how do plants distinguish between directions? Plants also have sensory organs? At present, scientists hope to use space science to reveal the mysteries of plant growth.
