Document Summary
Matured or ripened ovary surrounding the seed(s) Fruit wall (pericarp) develops from the ovary wall. Help disperse seeds by animals, wind, or water. Fruits do not provide any nutrients to the developing seeds. Example; peach, tomato, grains, nuts, and peas. Often the outer pericarp is fleshy and juicy but in many grains in nuts it may be thin and papery and fused to the seed coat. In the garden pea, the peas are the seeds and the surrounding pod is the pericarp. A berry has a thin exocarp, a soft fleshy mesocarp and an endocarp enclosing one or many seeds. A hesperidium is a berry with a tough, leathery rind. A pepo is a specialized berry with a tough outer rind (made of both receptacle tissues and exocarp), mesocarp and endocarp are all fleshy. A drupe has a thin exocarp, a fleshy mesocarp and a hard stony endocarp that covers the seed.
