WebNov 12, 2024 · Plants require light and water for photosynthesis to function. The animals have evolved responses known as tropisms to help them grow and find adequate light and water sources. In this case, the chances of survival for a plant are increased. A typism is a plant’s ability to adapt to its environment by changing its growth direction. WebOn Earth, aerial parts of the plant (shoots) grow upward while roots grow downward. However, the experiments showed that in a microgravity environment, the growth direction is unregulated, and some roots even extend in the same direction as the aerial stems (Figure 1).
