Question

Which one of the following statements is not correct?

Accepted Answer

Correct Answer: A — In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem.Step-by-step Solution:In potato (stem tuber), banana (corm/sucker), and ginger (rhizome), new plantlets arise from the nodes (not internodes) of the modified stem. Each node bears buds (called eyes in potato) that germinate to produce new plants. Internodes are simply the regions between nodes and do not bear buds or produce plantlets.Why other options are incorrect:Option B is correct — Water hyacinth (Eichhornia crassipes, the Terror of Bengal) grows prolifically and forms a dense mat on water surfaces, depleting dissolved oxygen through microbial decomposition of dead plant material, leading to death of aquatic organisms including fish. Option C is correct — offspring produced by asexual reproduction are genetically identical to the parent and to each other; they are called clones. Option D is correct — zoospores are microscopic, motile asexual reproductive structures with flagella, produced in water bodies by algae (e.g., Chlamydomonas) and some fungi.Key Concept: Vegetative propagation via modified stems: Nodes bear buds (not internodes). Potato: stem tuber (eyes = axillary buds at nodes). Ginger: rhizome. Banana: corm. Runners/stolons: nodes touch ground and produce new plants. Internodes = regions between nodes, no buds.
