Fruit Anatomy and Morphology

The primary function of a fruit is to protect the seeds from damage and to aid in their dispersal.

The pistil, which contains the ovary, develops into a fruit after fertilization.

The mesocarp is the fleshy part of a fruit that lies between the exocarp (skin) and the endocarp (innermost layer).

The exocarp is the hard, protective layer of a fruit that forms the outer skin.

The endocarp is the innermost layer of a fruit that surrounds the seeds.

Placentation refers to the arrangement of seeds within a fruit, such as marginal, axile, or parietal placentation.

A simple fruit develops from a single ovary and contains one or more seeds, such as an apple or a cherry.

An aggregate fruit develops from multiple ovaries of a single flower, resulting in a cluster of small fruits, such as a raspberry or a blackberry.

A multiple fruit develops from multiple ovaries of different flowers, resulting in a single fruit with multiple seeds, such as a pineapple or a fig.

An accessory fruit develops from the fusion of an ovary with other floral parts, such as the receptacle or the calyx, resulting in a fruit with a unique structure, such as an apple or a strawberry.

Dehiscence is the process by which a fruit splits open to release its seeds, such as the splitting of a pod or the opening of a capsule.

Dispersal is the process by which seeds are carried away from the parent plant by various means, such as wind, water, animals, or mechanical mechanisms.

Germination is the process by which a seed germinates and grows into a new plant, involving the absorption of water, emergence of the radicle, and development of the plumule.

Ripening is the process by which a fruit matures and becomes ready to be eaten, involving changes in color, texture, flavor, and nutritional content.

The exocarp, or the outer skin of a fruit, is often brightly colored and fleshy to attract animals for seed dispersal.
