Lỗ nước nhỏ trên lá sen đang nhỏ giọt nước trong làn sáng sớm.

Definition

1. Noun:
   • Hydatode: A specialized pore or small opening on the surface of a leaf or stem of a plant, through which water is exuded in a process called guttation.
   • Water hole / Water pocket: In general, non-technical usage, it can refer to a small natural depression or hole that holds water, such as a puddle or a small pond.

Usage Examples

• Noun (Botany):
  • Lỗ nước trên lá cho phép cây thải nước thừa. (The hydatode on the leaf allows the plant to excrete excess water.)
• Noun (General):
  • Trâu nằm mát bên cạnh một lỗ nước nhỏ. (The buffalo rested in the shade next to a small water hole.)

Advanced Usage
