A rhizome is a type of underground stem that grows horizontally. It serves as a storage organ and a means of vegetative reproduction for plants. Unlike roots, rhizomes can produce shoots and roots at various points along their length, allowing the plant to spread and colonize new areas. Common examples of plants with rhizomes include ginger, bamboo, and canna lilies. Rhizomes are important for plant survival, especially in challenging environments. They can store nutrients and energy, helping the plant survive adverse conditions like drought or winter. Additionally, rhizomes contribute to the formation of dense plant communities, which can enhance soil stability and biodiversity.
