Transpiration is a process similar to Evaporation. It is the loss of water in plants (leaves, stems, flowers, roots. Mostly leaves.) There are lots of tiny holes on the underside of plants, called stoma. Water evaporates through these holes, causing leaves & trees to go dry and brown. Amount of Transpiration depends on the light intensity, temp.,humidity, and wind speed. IS TRANSIPPERTION A TYPO FOR TRANSPIRATION? TRANSIPPERTION IS NOT A WORD!
