What are the methods used by plants to get rid of excretory products?
Plants get rid of the waste product in the following manner:
- Gaseous wastes, like CO 2 and O 2 , are expelled from the stomata
- Water vapour from the leaves through transpiration
- Solid wastes , stored in the plant body through shedding of leaves, peeling of bark, falling of fruits
- Gums and Resins excreted from the lenticels in the bark
Some wastes are excreted by the plant in the soil around them
