1. Water Absorption: Water and dissolved minerals are absorbed from the soil by the root hairs.
2. Xylem: The water and minerals then travel up the xylem, which is a network of vascular tissue that runs throughout the plant. Xylem is made up of dead cells with hollow, connected tubes.
3. Transpiration Pull: The water is pulled upwards through the xylem by a force called transpiration pull. This pull is created by the evaporation of water from the leaves through tiny pores called stomata.
4. Cohesion and Adhesion: The water molecules are held together by cohesion, the attraction between water molecules. They are also attracted to the walls of the xylem tubes by adhesion. These forces help to maintain a continuous column of water from the roots to the leaves.
5. Leaf Delivery: The water and dissolved minerals reach the leaves, where they are used in photosynthesis and other processes.
In summary: Transpiration is a vital process that allows plants to obtain essential nutrients and stay hydrated. The pull created by water evaporation from the leaves draws water upwards through the xylem, transporting it from the roots to the leaves.
