• A)Weak bonding between water molecules and the walls of xylem vessels or tracheids helps support the columns of water in the xylem.
• B)Hydrogen bonding between water molecules, which results in the high cohesion of the water, is essential for the rise of water in tall trees.
• C)Although some angiosperm plants develop considerable root pressure, this is not sufficient to raise water to the tops of tall trees.
• D)Most plant physiologists now agree that the pull from the top of the plant resulting from transpiration is sufficient, when combined with the cohesion of water, to explain the rise of water in the xylem in even the tallest trees.
• E)Gymnosperms can sometimes develop especially high root pressure, which may account for the rise of water in tall pine trees without transpiration pull.
