The protective seed coat surrounding the embryo provides protection from predators, physical damage, and desiccation during periods of drought; a supply of food in the form of stored nutrients within the seed enables the embryo to survive until conditions are suitable for germination; the ability to remain dormant allows the plant to time germination to coincide with favorable environmental conditions; and the ability to survive extreme drought ensures that the seed can remain viable under harsh conditions until favorable conditions return. All of these adaptations provide significant advantages for seed-producing plants.
