Simple Fruits

 These fruits can be divided into two types.

  1. Dry Fruits : In these fruits pericarp is not distinguished into three layers.  These are not fleshy.
  2.  Succulent fruits (Fleshy fruits) : In these fruits, pericarp is distinguished into three layers: epicarp, mesocarp and endocarp. Mesocarp is fleshy or fibrous. These fruits are indehiscent, so seeds are separated after decay of the flesh.
