Answer 2

Answer:

The correct answer is C) Velamen.

Explanation:

The outer covering of the epiphytic root is known as Velamen.  

Velamen, also called velamen radicum is spongy, multi-layered epidermis covering the roots of both epiphytic and semi epiphytic plants like an orchid. The function of the velamen is to provide mechanical support to the roots, thus providing protection to the vascular tissues of the root cortex, and it protects the root from loss of water due to transpiration.  

The velamen also protects the root cells from the destructive UV rays.
