WebA tropism is a directional growth response to a stimulus, for example to light, water, or gravity. These responses can be the result of cells growing longer, or elongating, but this is not always the case. Tropisms may actually cause a change in direction of growth by inhibiting elongation of cells.
WebWhen a plant moves toward the light, it’s called positive tropism. When a plant moves away from light, it’s called negative tropism. How do plants move? They do so with the help of chemicals called auxins. Think of auxins as an elastic band for cells. They help cells get longer and move.
