Velamen in Aerial Roots of Orchids
Velamen is a specialized type of layer found in the aerial roots of orchids. It is a spongy and water-absorbing tissue that helps the orchid plants to absorb moisture and nutrients from the air. The velamen layer is a unique adaptation of the orchid plants to their epiphytic lifestyle, which involves growing on other plants, rocks, or even wires, without any soil.
Structure of Velamen
The velamen layer is a multi-cellular tissue that covers the outer surface of the aerial roots of orchids. It is composed of several layers of dead cells that are modified to perform specific functions. The cells of the velamen layer are elongated and have thickened walls, which make them resistant to desiccation and mechanical damage. The velamen layer is also permeable to water and gases, allowing the roots to absorb water vapor and exchange gases with the atmosphere.
Function of Velamen
The velamen layer is an essential component of the aerial roots of orchids, as it enables them to absorb moisture and nutrients from the air. The velamen layer acts as a sponge, absorbing water vapor and other nutrients from the atmosphere. The water absorbed by the velamen layer is then transported to the inner tissues of the root, where it is used for various metabolic processes. The velamen layer also protects the root from desiccation, by preventing water loss through evaporation.
