Describe the process of phototropism
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. WebPhototropism is a response to the stimulus of light, whereas geotropism (also called gravitropism) is a response to the stimulus of gravity. Plants responses to gravity:
