Velamen in Orchids
Velamen is a specialized epidermis found in the aerial roots of orchids. It is a spongy, multi-layered tissue that protects the roots from dehydration and mechanical damage. The velamen is composed of dead cells that have a unique structure and function.
Structure of Velamen
The velamen is made up of several layers of cells that are filled with air. The outermost layer of the velamen is called the exodermis, which is a single layer of cells. The exodermis is covered with a waxy layer that helps to repel water and prevent the roots from becoming waterlogged.
Function of Velamen
The velamen plays an important role in the survival of orchids in their natural environment. Orchids are epiphytes, which means that they grow on trees and other plants rather than in soil. As a result, their roots are exposed to the air, and they must be able to absorb moisture from the air and rainwater that falls on the plant. The velamen helps to protect the roots from dehydration by absorbing moisture from the air and preventing it from evaporating.
Conclusion
