What are xylem? - Answer Tubes that carry water and mineral ions in solution; water travels upwards from roots to leaves. They are formed from dead cells. How is water transported in the xylem? - Answer THE COHESION-TENSION THEORY: 1)Water evaporates from the leaves- transpiration. 2)This creats tension which pulls more water into the leaf. 3)Water molecules are cohesive so the whole column of water moves upwards. 4)Water enters the stem via the roots. What is transpiration? - An...
