What is the cohesion-tension hypothesis?

Answer 1

The cohesion-tension theory describes how water moves from the roots to the leaf. Osmosis causes water to enter the xylem of roots from the soil. Due to the hydrogen bonding between the water molecules, water forms a string of molecules as it moves to the xylem. Constant transpiration at the top of the leaf pull the water molecules out of the plant. The differences in water potentials and pressures cause this fairly constant movement of water through the plant.

Answer 2

The cohesion tention hypothesis is based on a well known phonomena including the molecular properties of water and transpiration. The system exerts pressure that causes water and other mlecules to ooze out of a cut plants stem.

Answer 3

The cohesion-tension hypothesis explains how water moves through plants. It states that water is pulled up from the roots to the leaves through the xylem tissue due to the cohesive properties of water molecules and the tension created by water loss through transpiration at the leaves. This process helps maintain the plant's water balance and enables nutrient transport.

Answer 4

The cohesion-tension theory describes how water moves from the roots to the leaf.
