  1. Plants absorb water through their roots. The water moves up through the roots and the stem due to capillary action. In the leaves, water can exit the plant through special guard cells in the leaves that form a structure called a stoma (singular). These stomata (plural) open up, usually at night, and release water droplets. The droplets quickly evaporate from the leaf surface and enter the atmosphere (remember that evaporation is the process in which a liquid changes into a gas, in this case, liquid water changing into water vapor).

    Generally, people use the term "evaporation" to refer to water vapor that comes from lakes, rivers, streams, and other surface waters. In contrast, "transpiration" is the process in which water moves up from soil and through a plant ("trans" is a Latin root word that means through or across or beyond) and then out through the leaves where it evaporates and enters the atmosphere as water vapor. You will often hear the term "evapotranspiration" as well, which usually includes water that is transpired by plants as well as moisture evaporated from surface soils, but never actually passes through a plant.

    Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, and land slope.


  2. Transpiration. The plants have cells called stomata on the underside of their leaves.

    They let water evaporate out of these. It is almost like sweating.
