Plants do not excrete waste in the same way animals do, but they do have mechanisms to deal with waste products:
  • A: Storing the wastes: Plants can store waste products like resins, tannins, or certain other compounds in vacuoles, where they are kept in a non-toxic form.
  • B: Secretions: Some plants excrete waste through their leaves in the form of secretions such as oils, resins, or other substances. For example, some plants excrete excess salts through their leaves.
Plants do not produce urine (as in the case of animals), so C is not the correct answer.
Hence, D: Both A and B is the correct answer.

Understanding Excretion in Plants
Plants, unlike animals, do not have complex excretory systems. Instead, they have unique ways to manage waste products. The correct answer to how plants undergo excretion is option 'D' - both A and B.
Waste Management in Plants
Plants primarily excrete waste through two main methods:
  • Storing the Wastes:
    - Some waste products are stored in vacuoles or other tissues.
    - This method helps prevent the accumulation of toxic substances, ensuring that the plant remains healthy.
  • Secretions:
    - Plants can also excrete waste through secretions.
    - For example, certain plants secrete resins, gums, or essential oils, which can help in repelling herbivores or protecting against pathogens.

Why Not Urine Formation?
Plants do not form urine like animals. Instead, they rely on the following processes:
  • Photosynthesis:
    - During photosynthesis, plants convert sunlight into energy, producing oxygen as a by-product, which is then released into the atmosphere.
  • Transpiration:
    - Plants release water vapor through small openings called stomata. This process helps in cooling the plant and maintaining water balance.

Conclusion
In summary, plants excrete waste by storing waste materials and through secretions. They do not produce urine, making option 'D' the correct answer. Understanding these processes highlights the unique adaptations of plants in maintaining their health and balance in their environment.
