A plant cuticle is a protective film covering the epidermis of leaves. It consists of lipid and hydrocarbon polymers containing wax.
A cuticle is a protective film covering the epidermis of the leaves. Both the upper and lower epidermis are protected by this cuticle in many leaves, but leaves growing in dry areas have much thicker cuticles, serving as a structural support as well as protection.
"The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve." http://en.wikipedia.org/wiki/Retina

1.They are single cell thick 2.Thin film of moisture covering the alveoli allows the oxygen to dissolve in therefore making the process efficient 3. they have a large surface area 4.they are surrounded by network of blood capillaries maintaining the concentration gradient for the gaseous exchange
These small sac like structure are known as the alveoli . The alveoli help in the exchange of the gases, oxygen & carbon-dioxide,Lungs contain alveoli to increase the surface area and to easily transport oxygen to the blood vessels which surrounds the air sacs. Also, the air sacs have a thin film of oxygen which helps to absorb oxygen quickly.
