What are the methods used by plants to get rid of excretory products?
Plants use completely different strategies for excretion compared to animals. They get rid of gaseous wastes like oxygen and carbon dioxide through diffusion. To remove excess water, plants use the process of transpiration.
For other wastes, plants store them in cellular vacuoles. Some waste products are stored as resins and gums, especially in old xylem.
Plants also eliminate wastes by shedding parts. Waste products may be stored in leaves that fall off. Furthermore, plants excrete some waste substances into the soil around them.
Explanation
The answer is derived from section 5.5.2 'Excretion in Plants' and the summary provided in the 'QUESTIONS' section of the context. It highlights that plants do not have specialized excretory organs like animals. Instead, they rely on storage (vacuoles, resins, gums), removal of parts (falling leaves), and processes like transpiration and diffusion into the soil.
