This process is driven by the evaporation of water from the leaves, creating a negative pressure that pulls up more water from the roots to replace what has been lost. Advantages of transpiration The main advantages of transpiration are : ❏ Facilitates absorption and distribution of water and nutrients ❏ Maintains turgidity in plant cells ❏ Assists in cooling the plant and preventing overheating ❏ Contributes to the water cycle and influences climate patterns ❏ Maintains humidity levels in the atmosphere
