Question
Some plants excrete wastes through stomata, others through hydathodes. Name the processes occurring in them.
✓
Answer
When water is lost in the form of vapours through the stomata present on leaves, it is called transpiration. Some plants lose excess water in the form of liquid droplets from the margins of leaves, through hydathodes. This process is called as guttation. Hydathodes are structurally modified pores present on leaf margin.
