Transpiration is the process o watter muivement throu a plant an its evaporation frae aerial pairts, sic as leafs, stems an flouers.

Owerview o transpiration:
  1. Watter is passively transported intae the ruits an then intae the xylem.
  2. The forces o cohesion an adhesion cause the watter molecules tae form a column in the xylem.
  3. Watter muives frae the xylem inta the mesophyll cells, evaporates frae thair surfaces an leaves the plant bi diffusion throu the stomata
