Dead xylem vessels form continuous tubes for water transport. Living leaf cells lose water through transpiration, creating transpiration pull. This pull draws water upward through xylem against gravity, maintaining continuous movement from roots to leaves in plants.
Once water is absorbed by plant roots, it has to travel against gravity through xylem. How do the ‘dead’ cells of the xylem work together with the living cells of leaves at the top to keep the water moving?

Xylem vessels and tracheids are dead, hollow cells that form continuous tubes for water transport. Living cells in leaves lose water through transpiration from stomata, creating a suction force called transpiration pull. This pull draws water upward through xylem against gravity. Thus, dead xylem cells and living leaf cells work together to maintain continuous water movement.
