Transpiration

Transpiration

Transpiration is the process by which plants lose water vapor through small openings called stomata, primarily on leaves.

Functions of Transpiration

1. Water Transport: Pulls water and nutrients from roots to leaves.
2. Cooling: Reduces leaf temperature.
3. Gas Exchange: Facilitates CO₂ entry for photosynthesis.

Factors Affecting Transpiration

• Environmental: Temperature, humidity, wind, and light intensity.
• Plant Factors: Number of stomata, leaf structure, and water availability.

Transpiration is vital for plant growth and maintaining the water cycle.
