|
As water transpires from the leaves, a pull is created on the column of water in the xylem
|
|
|
Protein pumps move water across the cell membranes to restore osmotic pressure in cells
|
|
|
Water is moved from turgid cells adjacent to water-deficient cells in the phloem tissues
|
|
|
Water molecules bond to minerals which are then transported upwards
|
Detailed explanation-1: -The suction force (negative pressure) created by transpiration from the leaves’ surface draws water from the soil and roots through the xylem. Water is sucked up as a result of the xylem vessel . Due to the appearance of capillary action, transpirational pull moves water from roots to leaves.
Detailed explanation-2: -The “stickiness” between water molecules and the xylem vessel walls is called adhesion. Cohesion and adhesion work together in the xylem to pull water molecules from the roots, up the stem, and out of the plant through the stomata. The flow of water transport is impacted by the plant rate of transpiration.
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.
