Question

Which one of the following statements is not correct?

• A. Microscopic, motile, asexual reproductive structures are called zoospores.
• B. Water hyacinth, growing in the standing water, drains oxygen from water that leads to the death of fishes.
• C. Offspring produced by the asexual reproduction are called clone.
• D. In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem.

Answer 1

The correct option is D In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem.

Potato, banana and ginger propagate vegetatively by their modified stems. Potato propagates by tuber which has buds over its eyes or nodes. These buds produce new plantlets. Banana and ginger propagate with the help of rhizomes which also have buds on nodes for the formation of new plantlets.
