Growing Plants Know Right from Left
Plants seem to know which way is up and which way is down；furthermore, they seem to know right from left.If a cutting from a Lombardy poplaris kept alive, new shoots will grow from the end that grew uppermost in the tree.
There is no visible difference between the top and the bottom of the living stick, even under a microscope.Even so, the stick will not send out shoots from the end it views as bottom even if this end happens to be on top！
Scientists, studying this subject further split their cuttings lengthwise.To their surprise, they made another interesting discovery.A good many more buds grew on the right-hand side of the split surface than on the left.They split the sticks again and found that the buds again grew on the right side.
The results of the entire study showed a 60-40 preference for the right side, proving that growing plants are basically “right-handed”。
