Describe the movement of the stem and root under the influence of the gravitational force of the earth. Define positive and negative geotropism

Plants have a certain ability to guide the root and stem in the right direction. The root moves to the center of the earth, and the stem moves in the opposite direction. If you plant a tree at an angle, then the root will begin to grow not to the side, but downward. This is very important for the life of all plants. Scientists were able to use this property to create ornamental trees. Trees are planted with their roots up. The stem and root change roles, but due to geotropism, the branches grow downward. But not all plants are able to take root.
