Answer:
Explanation:
Vegetative Propagation by Stems
Vegetative propagation occurs through stems when new plants arise from the nodes. This is where buds are formed, which grow into new plants. Stems that grow horizontally on the ground are called runners. As these runners grow, buds form at the nodes, which later develop the roots and shoots, resulting in the formation of a new plant. Example – Cyanodon; Mint etc.
The bulb is the round, swollen part of the underground stem. Within the bulb lies the organ for vegetative propagation such as the central shoot that grows into a new plant. Bulbs have a bud surrounded by layers of fleshy leaves. A few examples include Onions, Garlic, and Tulips, etc.
We can find stem tubers in plants like potatoes. This part is the swollen apical part containing many nodes or eyes. Every eye has buds. New plants originate from these buds.
