Transpiration

증산작용

Definition

The evaporation of water from plant leaves through stomata, creating a pulling force that draws water up from roots.

Detailed Explanation

Transpiration drives the movement of water from soil through plant to atmosphere — a single large tree transpires hundreds of liters per day. This "transpiration stream" also carries dissolved minerals from roots to leaves. Forests generate their own rainfall by recycling moisture through transpiration, making deforestation self-reinforcing: losing trees reduces rainfall, which prevents forest regeneration.
