Question
Place the steps of the cohesion-tension hypothesis of long-distance water movement in the they occur, beginning with the opening of the stomata. order in which Stomata open in leaves. Water enters roots. Water potential is lower outside of the leaf than inside Water evaporates from mesophyll cell walls within the leaf. Tension is created at the air--water interface. Water potential within the leaf lowers. Water is pulled out of the xylem into the leaf Capillary action pulls the water column up in the xylem Water enters the root xylem.Explanation / Answer
Stomata open in leaves
water evaporates through the stomata in the leaves.
it creates a negative pressure (also called tension or suction) in the leaves and tissues of the xylem.
The negative pressure exerts a pulling force on the water in the plant’s xylem
It draws the water upward.When water molecules stick to one another through cohesion.
they fill the column in the xylem and act as a huge single molecule of water.
In plants, adhesion forces water up the columns of cells in the xylem and through fine tubes in the cell wall.
Water moves from stem to leaves due to tension created in leaves.
Then water moves from roots to stem due to tension created in stem.
Water moves from surrounding to roots due to tension created in roots.
