What is transpirational pull?

उत्तर
As water is lost from the leaf surface by transpiration, more water molecules are pulled up due to the tendency of water molecules to remain joined, i.e., cohesion. This produces a continuous column of water throughout the stem, which is known as the 'transpiration pull'.
