Answer:
Step-by-step explanation:
Water moves from the soil to the leaves in a tree through a process called transpiration. First, water is absorbed from the soil by the roots of the tree and is transported upward through the xylem vessels of the stem. This movement is driven by the cohesion-tension mechanism, which is a combination of the cohesive properties of water molecules and the tension created by the evaporation of water from the leaves.
As water evaporates from the leaves through small openings called stomata, it creates a negative pressure that pulls more water up from the roots. This negative pressure is transmitted through the water column in the xylem vessels, which helps to maintain the continuous flow of water from the soil to the leaves.
In addition, the process of transpiration also helps to cool the leaves of the tree and supply them with the necessary nutrients for photosynthesis. As water is pulled up through the xylem vessels, it brings along dissolved minerals and nutrients from the soil, which are used by the plant for growth and energy production.
Overall, the movement of water from the soil to the leaves in a tree is a complex and vital process that allows the plant to survive and thrive in its environment.
