The phenomenon in which different parts of the plant, like root, stem and leaves, develop into new plants under appropriate conditions is called _________.
Vegetative propagation
Correct Answer: Vegetative propagation
Vegetative propagation is a type of asexual reproduction in plants where new plants develop from vegetative parts (roots, stems, leaves, buds) without the involvement of seeds or spores.
Examples:
- Stem: Potato (tubers), ginger (rhizomes), sugarcane (stem cuttings)
- Root: Dahlia, sweet potato
- Leaf: Bryophyllum (buds on leaf margins)
This is different from regeneration (repair/regrowth in animals like Hydra, Planaria) and sexual reproduction (involves gametes).
