Interfaces in Object Oriented Programming Languages. An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). For example, say we have a car class and a scooter class and a truck class. Each of these three classes should have a start_engine() action.
The epidermis is the very outer layer of the skin that provides protection from bacteria (thanks to it's pH level), becoming overloaded with water (it's waterproof) and from heat loss. It has four of five distinct layers to achieve this.
Abstract. The epidermis is the protective outer layer of clonally related cells covering all plant organs. It is composed of a number of specialised cell types which differentiate from the basal epidermal cell in adaptively significant frequencies and patterns.lant epidermis fulfils a basic protective function, but specialised cells within the epidermis have specific roles. The aerial epidermis originates in the shoot apical meristem, the root epidermis in the root apical meristem and the seedling epidermis arises by isolation of the outer layer during embryogenesis.
