(N/A) Transpiration is the loss of water in the form of water vapor from the aerial parts of the plant,primarily the leaves.
Significance of transpiration:
$(i)$ Cooling effect: Transpiration helps in cooling the plant surface,especially during hot weather,as the evaporation of water consumes heat energy.
$(ii)$ Transport of water and minerals: It creates a transpiration pull (a suction force) that helps in the upward movement of water and dissolved minerals from the roots to the leaves.
$(iii)$ Distribution of water: It ensures the continuous supply and proper distribution of water and essential nutrients throughout the plant body.
$(iv)$ Maintenance of turgidity: It helps in maintaining the turgidity of cells,which is essential for the structural support and growth of the plant.
