Answer: A peach is a drupe (same classification as a mango). Beginning at the outside of the fruit and working to the interior, the outer skin of the fruit is called the exocarp. The inner flesh is called the mesocarp and the stony pit is called the endocarp. The presence of the pit is what distinguishes “stone fruits” (i.e., peach, plum, cherry, apricot) from “pome fruits” (i.e., apple, pear, etc.). Inside the stony endocarp (pit) is the seed.
