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
