what role does transpiration play in plants?
Transpiration is a significant process in plants. Some of the beneficial roles are:
Mineral transport: Transpiration creates a transpiration pull which helps to transfer minerals upwards.
Gaseous exchange: Stomata absorb carbon dioxide while transpiring for photosynthesis
Cooling effect: Transpiration like evaporation has cooling effect on plants
Water transport: The transpiration pull transports water from roots to leaves
Turgor pressure: Transpiration maintains optimum turgor pressure in plant parts to facilitate growth
