What are the methods used by plants to get rid of excretory products?
Wastes excreted from plants are: (i) Gaseous wastes–through stomata pores CO2 is given out during respiration and O2 is given out during photosynthesis. (ii) Liquid wastes (water)–through stomata pores by transpiration. (iii) Other wastes–are stored in leaves dead cells and the leaves fall off. Some other waste products are stored as resins and gums in old xylem of the plant and other wastes are also thrown out from nodes into the soil.
