Bryophyllum
Explanation
Vegetative propagation is a mode of asexual reproduction in plants where new individuals arise from vegetative parts such as roots, stems, or leaves, rather than from seeds. Different plant species utilize specific structures for this process.Analysis of Options:
- Dahlia: Incorrect. Dahlia reproduces vegetatively through fasciculated tuberous roots. These swollen roots store food and can give rise to new plants when detached.
- Sweet potato Sweet potato: Incorrect. Sweet potato reproduces through fleshy roots (root tubers). Adventitious buds present on these roots grow into new shoots.
- Bryophyllum: Correct. Bryophyllum reproduces through adventitious buds located in the notches along the margins of its leaves. When the leaf falls on moist soil, these buds develop roots and shoots, eventually forming independent plants.
- Turmeric: Incorrect. Turmeric reproduces through rhizomes, which are modified underground stems. These stems grow horizontally and produce new shoots and roots from their nodes.
Key Takeaway: Bryophyllum is a classic example of vegetative propagation via leaves, where adventitious buds develop along the leaf margins and detach to form new plants.
