Which one of the following statements is not correct?
Correct answer: C. In potatoes, bananas, and ginger, the plantlets arise from the internodes present in the modified stem
- A. Offspring produced by asexual reproduction are called clones
- B. Microscopic and motile asexual reproductive structures are called zoospores
- C. In potatoes, bananas, and ginger, the plantlets arise from the internodes present in the modified stem
- D. Water hyacinth, growing in standing water, drains oxygen from water leading to the death of fishes
Explanation
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. Cloning is the process of producing individual organisms with identical or virtually identical DNA, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction. In simple context, clone can are a single cell or a group of cells that are genetically identical to its ancestor cell or group of cells.Zoospores use a flagellum for locomotion and are created by some protists, bacteria, and fungi to propagate themselves.Water hyacinth is a type of invasive floating plant found in water bodies across the world. These invasive species block the sunlight reaching and oxygen level in water systems, which results in damaging water quality and seriously affecting various lifeforms in the ecosystem.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
