Epidermis
is one of the cover tissues on a plant surface. Cover tissues have a
protection role: from external conditions such as drought, high and low
temperature, strong insolation, mechanical damage, invasion of
microorganism and other. There are two types of cover tissues:Primary
cover tissue - emerges from protodermis, and create inside and outside
covers. Outside cover is made of single-layer epidermis and hypodermis
(multi-layered parenchyma tissue which emerge from the sub-epidermal
bark parenchyma) together. Inside cover is made of endodermis, which
separates transmissible organs from the bark parenchyma.Secondary
cover tissue - emerges from the cork cambium - phellogen (secondary
meristem tissue). These are cork (phellem) and dead bark (lila, lup,
rhytidome).
