CUTICLE LAYER OF A PLANT:


This is the cuticle layer of a plant in which the leaves secretes a waxy substance that forms a coat so it helps to minimize water loss and reduce pathogens to enter the leaves. It also helps the plants leaves from getting too wet or too dry. Also, as you can see the waxy substance can be seen because when water is added the leaf instead of absorbing the water it turns into little beady drops that fall off.
