WebMay 9, 2024 · For example, when a seedling is turned on its side, the root grows gradually downward creating a curvature, an example of positive gravitropism. This occurs in the growing region of the root, a region located close to the root tip. Once the root tip points downward again, the root stops curving and the subsequent growth is straight.
