Cây cối thoát hơi nước qua các lỗ nhỏ trên lá.

Definition

Noun: - Transpiration: The biological process in plants where water is absorbed by the roots, moves through the vascular system, and evaporates as water vapor from the aerial parts, primarily through pores called stomata. This process is crucial for nutrient transport and temperature regulation.

Usage Examples

• Noun:
  • Thoát hơi nước là một quá trình sinh lý quan trọng ở thực vật. (Transpiration is an important physiological process in plants.)
  • Tốc độ thoát hơi nước tăng lên trong điều kiện nắng nóng. (The rate of transpiration increases under hot, sunny conditions.)
  • Lá cây là cơ quan chính thực hiện thoát hơi nước. (Leaves are the main organs performing transpiration.)

Advanced Usage
