My research field is about mechanics. Somebody told me that the
sunflower's movement is caused by the different growth rates of cells,
which is affected by the sunlight. But it seems to be impossible from the
mechanics opinion, so I want to to know the real principle and the details
about the sunflower's movement. Thanks a lot!
