The term PERICARP refers to the outer layer of a fruit, which can also be referred to as a SHELL, BUR, POD, or SEEDCASE. The pericarp is the protective layer that surrounds the seeds of a fruit and helps to protect them from the environment. It is made up of several layers, including the exocarp, mesocarp, and endocarp. The exocarp is the outermost layer, which is often referred to as the skin or rind. The mesocarp is the middle layer, which is often fleshy and edible. The endocarp is the innermost layer, which is often hard and protects the seeds.
