Plants use several methods to get rid of excretory products:
- Leaf Shedding: Waste products are accumulated in leaves which are eventually shed.
- Gum and Resin Secretion: Excretes waste substances as gums and resins.
- Stomatal Excretion: Some gaseous wastes are released through stomata.
- Lenticels: Gaseous wastes can also be expelled through lenticels in the bark.
