WebDec 3, 2024 · Tropism is a multiscale dynamic process: The stimulus takes place at the plant or organ level and its information is transduced down to the cellular level, creating a tissue response through shape-inducing mechanical forces that change the shape of …
WebJun 1, 1999 · 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, where they can reach out to take up the water and mineral ions required for plant growth and development.
