Il seme è l'organo di propagazione delle spermatofite a cui è affidata la disseminazione delle piante. Deriva dalla trasformazione di un ovulo dopo la fecondazione. In genere si sviluppa sulla pianta madre e se ne distacca dopo la maturazione. I semi sono di solito parti vegetali che contengono pochissima acqua (i semi di senape il 7%, i semi di ricino il 6%), caratteristica che ne garantisce la lunga conservabilità.
