transpiration

• اسم يشير إلى عملية انتقال الماء داخل النبات من الجذور إلى الثغور الصغيرة في السطح السفلي للأوراق، حيث يتحول إلى بخار ويُطلق في الغلاف الجوي. ويُستعمل أيضًا بمعنى إخراج البخار أو الرطوبة من الكائن الحي إلى الوسط الخارجي.

A noun referring to the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
