Transport water to the leaves

Detailed explanation-1: -Xylem is the vascular vessel which transports water from the roots to the leaves where it is used for the process of photosynthesis. In the absence of xylem, water will not reach the leaves and thus, photosynthesis won’t take place for it needs 6 H2O.As a result the plant wilts and dies.
Detailed explanation-2: -The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw. Cohesion (water sticking to each other) causes more water molecules to fill the gap in the xylem as the top-most water is pulled toward the stomata.
Detailed explanation-3: -Xylem transports water in plants. Water is absorbed from the soil through root hair cells. Water moves by osmosis from root cell to root cell until it reaches the xylem. It is transported through the xylem vessels up the stem to the leaves.
