Transpiration

Transpiration is the process by which a plant loses water primarily from
leaf stomata. Transpiration is a necessary process that uses about 90
percent of the water that enters the plant through the roots.
Transpiration is necessary for mineral transport from the soil to the
plant parts, for cooling plant parts through evaporation, to move sugars
and plant chemicals, and to maintain a turgor pressure. The amount of
water lost from the plant depends on several environmental factors, such
as temperature, humidity and wind or air movement. As temperatures or
air movement increase, transpiration increases. As humidity decreases,
transpiration increases.



In the winter time The plant reduces both transpiration and respiration
processes. The plant still needs the water intake from other sources;
such as the relative humidity from a water dish in the winter time as
the stomata (this reduces transpiration) will open to increase to take
in water vapor for photosynthesis needs.


hope this helps,
