<em>the function of epidermis is to protect the leaf
make it air tight
prevent water loss as it is waxy
also it is transparent and allows all light to enter...
chloroplast is required for carrying out process of photosynthesis...
as epidermis is not specialized to carry out photosynthesis... so it does not have any chloroplast...</em>
Nerves that detect deep pressure are called Pacinian corpuscles.
Pacinian corpuscles are microscopic onion-shaped nerve structures that are situated in the dermis and hypodermis. Pacinian corpuscles detect deep pressure and vibration. This nerve has a myelinated nerve ending in the middle of its structure and the external layer contains flattened cells, a lymph-like fluid and collagen fibers. The structure of pacinian corpuscles provides a fast response and rapid recovery by transmitting fast events. This make them sensitive to pressure and vibration.
