Seed.
Botanically, a seed is a mature fertilized ovule containing an embryonic plant; usually it has nutrient storage tissue and is surrounded by a protective coat, the testa. This structure is a "true seed"; however, the ovules of many species have additional structures of the mother plant attached or fused to the seed coat. For example, the "seed" of Triticum aestivum (wheat) is botanically a fruit because the pericarp (ovary wall) is fused with the seed coat. In these rules the term "seed" will be used in the agronomic sense (i.e. the true seed plus any accessory structures that may be attached when it is planted in the field; see section 3.2 of the AOSA Rules for Testing Seeds Vol. 1).

fruit
Fruit.
The structure that develops from the pericarp as the enclosed seed or seeds mature. Fruits may have the following attributes: Succulent or dry, depending on whether or not the middle layer of the pericarp (mesocarp) develops into a fleshy covering; Dehiscent or indehiscent, according to whether or not the fruit wall splits open to release the seed; True or simple fruits, which develop from the gynoecium of a single flower, and multiple fruits, which develop from a complete inflorescence; Monocarpellary or polycarpellary, depending on whether they developed from a single ovary or from a number of fused ovaries.
ISTA Handbook on Pure Seed Definitions, Glossary. 3rd Edition 2010
