The correct option is Bryophyllum.
Explanation
Vegetative propagation is a form of asexual reproduction in plants where new individuals arise from vegetative parts such as roots, stems, or leaves. This process allows plants to reproduce without the formation of seeds or spores.
Detailed Analysis:
- Bryophyllum (Correct): This plant is a classic example of vegetative propagation through leaves. It develops adventitious buds in the notches along the margins of its leaves. When a leaf falls on moist soil, these buds develop roots and shoots, eventually growing into independent new plants.
- Hibiscus (Incorrect): Hibiscus is typically propagated through stem cuttings (artificial vegetative propagation) or sexually through seeds. It does not possess the ability to generate new plants from leaf margins.
- Wheat (Incorrect): Wheat is a monocotyledonous crop that reproduces sexually through seeds (grains). It does not undergo vegetative propagation via leaves.
- Mango (Incorrect): Mango trees reproduce sexually through seeds or are propagated vegetatively using grafting techniques involving the stem (scion and stock). They do not produce adventitious buds on leaves for reproduction.
Key Takeaway:
Bryophyllum reproduces vegetatively through epiphyllous buds (adventitious buds) located at the notches of its leaf margins, which can sprout into new plantlets upon contact with soil.
