Mesocarp

Mesocarp is the middle layer of the pericarp of a fruit, which is directly in contact with the seeds. It is derived from the ovary wall of the flower and is found in between the exocarp (outer layer) and endocarp (inner layer). The mesocarp is often the fleshy part of the fruit, which is consumed by humans and animals.

Structure and Function

The mesocarp is typically the largest part of the pericarp and can vary in texture and thickness depending on the type of fruit. In some fruits, like peaches and plums, the mesocarp is juicy and sweet, while in others, like avocados, it is creamy and rich. The mesocarp serves several functions in the fruit, including protecting the seeds, aiding in seed dispersal, and providing nutrients for the developing seeds.

Types of Mesocarp

There are several types of mesocarp, including:

• Fleshy Mesocarp: This type of mesocarp is found in fruits like peaches, plums, and cherries. It is juicy and sweet, and is the part of the fruit that is typically consumed.

• Dry Mesocarp: This type of mesocarp is found in fruits like nuts and beans. It is hard and tough, and is not typically consumed.

• Fibrous Mesocarp: This type of mesocarp is found in fruits like coconuts. It is tough and fibrous, and is not typically consumed.
