Correct option is B
Sol: The correct answer is (b) Numerous waste products from plants are stored in centrioles.
Key Points:
- Centrioles are cell structures involved in cell division in animal cells and certain lower plants. Plants typically store waste products in vacuoles, not centrioles.
- Centrioles are cellular structures found in animal cells and some lower plant cells. They play a critical role in cell division by helping to organize the assembly of microtubules during mitosis and meiosis. However, centrioles are not involved in the storage of waste products.
- Plant Waste Storage: In plants, waste products are commonly stored in vacuoles. Vacuoles are large, membrane-bound organelles that serve various functions, including storage of waste materials, maintaining turgor pressure, and sequestering harmful substances.
- Other Excretory Products: Plants also excrete waste through processes like shedding leaves, exuding resins, gums, and latex. These substances can contain metabolic waste products.
All other options:
Transpiration is the mechanism by which a plant eliminates surplus water.
True. Transpiration is the process by which water is absorbed by plant roots, moves through plants, and evaporates from aerial parts like leaves.
Photosynthesis produces oxygen as a by-product.
- True. During photosynthesis, plants convert carbon dioxide and water into glucose and oxygen, with oxygen being a by-product.
Gum is an excretory product of plants.
True. Gum is one of the excretory products of plants, along with resins and latex.
