Plant Biology
Transpiration
The process by which water evaporates from plant leaves through stomata. Transpiration drives water movement from roots to leaves and helps cool the plant.
Biological Context
A large tree can transpire hundreds of liters of water daily. The transpiration stream carries dissolved minerals from roots to leaves. Stomata balance water loss against CO2 uptake for photosynthesis. Drought stress occurs when transpiration exceeds water uptake.
Business Application
Organizational transpiration: the constant outflow of resources (cash, talent, attention) that drives circulation through the system. Too much transpiration without adequate intake causes organizational drought stress.
