Step 1: Understand waste disposal mechanisms in plants.
Plants do not have specialized excretory organs like animals. They use various methods to remove or store waste products:
Transpiration: Excess water is removed through stomata as water vapor.
Storage: Some waste products like gums, resins, tannins, and latex are stored in dead cells, bark, leaves, or other parts that eventually fall off.
Secretion: Some wastes are secreted through roots into the soil.
Shedding: Plants shed leaves, bark, and fruits containing accumulated wastes.
Step 2: Analyze each statement.
(A) Excess water is given out by transpiration: Correct. Transpiration is the process by which plants lose excess water vapor through stomata.
(B) Gums and Resins are wastes that are stored: Correct. Plants store waste products like gums, resins, tannins, and alkaloids in various parts such as bark, leaves, or specialized cells.
(C) Roots secrete some wastes into the soil: Correct. Some plants secrete metabolic wastes through their roots into the surrounding soil.
(D) Flowers can store some waste products: Incorrect. Flowers are reproductive structures and are generally not used for waste storage. Waste products are typically stored in non-essential parts like bark, old leaves, or fruits that will be shed. Flowers are delicate structures involved in reproduction and pollination, not waste accumulation.
Step 3: Conclusion.
Statement (D) is incorrect because flowers are not used for storing waste products. Waste storage occurs in older leaves, bark, resins, gums, and other non-essential parts.
Final Answer: (D) Flowers can store some waste products.
