However, plants are actually even more active in responding to the factors WebJun 1, 1999 · Update on Development. Since 1806, we have known that plant organs use gravity as a guide for growth ( Knight, 1806 ). The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. It also directs roots to grow downward in soil ...
