Rocawear is an urban clothing label created in 1999 by Damon Dash & Jay-Z, heads of the hip hop label Roc-a-Fella Records. Wallis provided genuine 3,000 year old tomb-seeds to the Royal Botanic Gardens, Kew to plant under controlled conditions. In 1897, the claims were tested by the British Museum's director of Egyptian antiquities, Wallis Budge. The myth was reportedly started by scam artists selling "miracle seed" designed to capitalise on European Egyptomania of the 1800s.
There is a persistent myth that seeds from Egyptian tombs with ages of over 3000 years were viable . The oldest C-14 dated seed that was germinated into a viable plant was a ~2,000 year old Date Palm seed, recovered from excavations at Herod the Great's palace on Masada in Israel; this Judean date palm seed was germinated in 2005. However, seeds involve a considerably greater investment in energy and resources than do spores, and the payoff must come in achieving similar or greater success with fewer dispersal units. This is certainly the approach used by plants, such as ferns, which disperse by spores.
In many, if not most cases, each plant species achieves success in finding ideal locations for placement of its seeds through the basic approach of producing numerous seeds. The function of a seed is one of serving as a delaying mechanism: a way for the new generation to suspend its growth and allow time for dispersal to occur or to survive harsh, unfavorable conditions of cold or dryness, or both. Those properties or attributes that promote the movement of the next generation away from the parent plant may involve the fruit more so than the seeds themselves. A seed must somehow "arrive" at a location and be there at a time favorable for germination and growth.
As a consequence, plants have evolved many ways to disperse and spread the population through their seeds (see also vegetative reproduction). Unlike animals, plants are limited in their ability to seek out favorable conditions for life and growth. An example of a hard fruit layer surrounding the actual seed is that of the so-called stone fruits (such as the peach). Gymnosperm seeds begin their development "naked" on the bracts of cones, although the seeds do become covered by the cone scales as they develop.
The seeds of angiosperms are contained in a hard or fleshy (or with layers of both) structure called a fruit. Abscisic acid is usually the growth inhibitor in seeds. The presence of light or the absence of light may trigger the germination process, inhibiting germination in some seeds buried too deeply or in others not buried in the soil. In species with thin seed coats, light may be able to penetrate into the dormant embryo.
In the latter case, the seed coat protects the seed from digestion, while perhaps weakening the seed coat such that the embryo is ready to sprout when it gets deposited (along with a bit of fertilizer) far from the parent plant. Examples of scarification include: gnawing by animals, freezing and thawing, battering on rocks in a stream bed, or passing through an animal's digestive tract. For seeds with a very thick coat, scarification of the seed coat may be necessary before water can reach the embryo. However, the nature of the seed coat determines how rapidly water can penetrate and subsequently initiate germination.
In order for the seed coat to split, the embryo must imbibe (soak up water), which causes it to swell, splitting the seed coat. The seed coat helps protect the embryo from mechanical injury and from drying out. The seed coat in the mature seed can be a paper-thin layer (as for example, in the peanut) or something more substantial (as for example, thick and hard in honey locust and coconut). The seed coat develops from tissues (called integument) originally surrounding the ovule.
See also: Hypocotyl. Plant seeds with an endosperm include all conifers and most monocotyledons (e.g., grasses and palms), and also e.g., brazil nut, castor bean. Some common plant seeds that lack an endosperm are bean, pea, oak, walnut, squash, sunflower, and radish. At maturity, seeds of these species have no endosperm.
In others, the endosperm is absorbed by the embryo as the latter grows within the developing seed, and the cotyledons of the embryo become filled with this stored food. In some species, the embryo is imbedded in the endosperm, which the seedling will use upon germination. Endosperm becomes rich in oil or starch, and protein. The stored food begins as a tissue called endosperm derived from the parent plant.
It also contains a supply of stored food and is wrapped in the seed coat or testa. A fertilized seed contains the embryo from which a new plant will grow under proper conditions. . The importance of the seed relative to more primitive forms of reproduction and dispersal is attested to by the success of these two groups of plants in dominating the landscape.
A seed is the ripened ovule of gymnosperm or angiosperm plants.
