The scientific term for the movement of water through a plant is transpiration. This process involves the evaporation of water from plant surfaces, primarily leaves, which creates a negative pressure that draws water upward from the roots through the xylem vessels. Transpiration is vital for maintaining plant temperature, facilitating nutrient transport, and aiding in the overall water cycle within ecosystems. Additionally, it contributes to the flow of water in the soil-plant-atmosphere continuum, making it crucial for plant health and growth.
