Question

Explain the role of hydrogen bonding in transpiration pull.

a) Hydrogen bonding facilitates water absorption by roots
b) Hydrogen bonding helps in the cohesion of water molecules in the xylem
c) Hydrogen bonding prevents water loss during transpiration
d) Hydrogen bonding is not related to transpiration

Answer 1

Cohesion and adhesion are important for the transport of water from the roots to the leaves in plants.

Step-by-step explanation:

Cohesion and adhesion are important for the transport of water from the roots to the leaves in plants. As water molecules are evaporated from the surface of leaves, they tend to stay connected to water molecules below them, creating a "pull" up the water column. Ultimately, water is pulled into the roots, allowing the plant to receive the dissolved minerals they require from the soil.
