Plants excrete:
Correct answer: D. All (A), (B) and (C)
- A. Excess water
- B. Excess oxygen
- C. Excess carbon dioxide
- D. All (A), (B) and (C)
Explanation
In contrast, the mechanism of excretion in plants is diferent. Plants in their autotrophic mode of life produce oxygen and in metabolism produce C02 and H2 0 as the excretory products. Plants also produce several organic and inorganic compounds which are stored for various purposes and are also removed when necessary. Plant cells have large vacuoles; these can be used for either storage of useful compounds, or the storage of waste substances. These may accumulate at the concentrations that lead to crystal formation in the vacuoles. Plants produce certain wastes of inorganic and organic nature, which are stored in certain organs.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
