Question

In case tunica is multilayered, which is likely to happen.

• A. All layers take part in formation of multilayered epidermis
• B. All the layers produce cortex
• C. Outer-most layer forms hypodermis, middle layer cortex and inner layer endodermis
• D. Only the outermost layer forms the epidermis

Answer 1

The correct option is D Only the outermost layer forms the epidermis

When the tunica is multilayered, then the condition is known as multistratose tunica. The layers of tunica can be designated as L1, L2, L3, etc. The L1 i.e. the outermost layer of the tunica will rise to the epidermis. Thus the rest of the layers would form the cortex and the vascular tissues, as seen in Datura.

Hence, the correct answer is D.
