The fruit known for having a pit surrounded by a fleshy outer layer is the drupe, commonly referred to as a stone fruit. Examples of stone fruits include peaches, cherries, and plums. The pit, or stone, inside is hard and encases the seed. Drupes are characterized by their juicy and often sweet flesh, making them a popular choice for snacking and cooking. Their distinct structure allows for easy differentiation from other fruit types, such as berries or pomes. The delicious flesh of drupes typically attracts animals, which help in seed dispersal, contributing to the plant's reproduction.
