The biggest seed I ever saw is a coconut.

Check this - not the familiar kind of coconut, but a seed from a coconut palm nonetheless\n\nhttp://news.bbc.co.uk/1/hi/scotland/3153327.stm

no it doesnt , some fruites are huge but only have one seed inside for example the durian which is located in singapore ,china,tailand ....kiwi on the other hand is small but has lots of seeds

It was unknown.  Many health practitioners referred to simply "  the mans seed."

pip\n\nThat's what we always used to call seeds when I was young, it may be a UK english thing.

Do you mean heaviest?  Currently, it has to be that new guy....I don't remember his name.....that is bigger than the Giant.

Actually I could not find anything either. Closest I found was:\n\nDianantha: Otherwise it could be derived from dianthus, the name of a type of flower (from Greek meaning "heavenly flower").

The seeds have "helicopters", which are called Samaras in botannical terms.\nThey are carried away from the tree by the wind.

The largest egg ever discovered was laid by the now extinct, flightless elephant bird. This 13- by 9.5-inch (33- by 24.1- centimeter) egg held over 2 gallons (9 liters) of liquid. That's eight times as much as an ostrich egg.\n\nThe ostrich egg is the largest egg in the world today.\n\nThe kiwi bird lays the largest egg in proportion to its body size. It would be as if a human gave birth to a 43-pound (19.5-kilogram) baby. No wonder the female lays the egg, and the male has to sit on it.

http://waynesword.palomar.edu/ww0602.htm\n\nThe world's largest flower, called Rafflesia, can have a diameter up to one meter and can weigh up to 10 kilograms. It also smells like rotting flesh. Discovery News tells us that its genetic roots have been uncovered and that this plant that smells so bad is related to delicate flowers such as poinsettias or violets.

There are Ceiba trees at the ruins ... they have pods with many seeds surrounded by a dense mat of cottony fibers. Does this fit? Or it could be a legume (bean-like seed?) of some sort or a member of Bignoniaceae (flat winged seed?). If it is 9 months old it hasn't faced a full Canadian winter yet, I hope you are going to protect it!

its a wonder\n\n!\n\nto know it\nThe seeds are carried away from the mother plant by animals called dispersers. In some cases the animal carries away an entire fruit, in other cases the animal is carrying seeds alone. The animal usually feeds on the fruit (ovary wall), but "tosses" the seeds (or passes them through its digestive system). This assures that seeds end up far away from the "mother" plant, where they can develop without competition from "mom."\n\nHaving been taken away from the parent, it is time for the seeds to sprout or germinate. Seed germination is defined as the emergence of the radicle through the seed coat. Common garden seeds germinate if given just water and reasonably warm temperatures.\n\nWild species usually have some kind of deeper dormancy to avoid sprouting in late summer or fall when the seeds are commonly dispersed. This assures that tender seedlings are not frozen at a young age by the approaching winter. Instead the seedlings do not appear until warm weather arrives in springtime.\n\nIf a species has evolved a very thick seed coat, it may require scarification of that seed coat before water can enter the seed and initiate germination. Perhaps the coat has to be gnawed at by animals, or frozen and thawed repeatedly to crack the coat, or rund down the rocks in a stream bed or up beach in pounding surf to wear the coat down. Perhaps the seed is swallowed whole by the disperser. The thick seed coat protects the dormant embryo as it passes through the animal's digestive system. The weakening of the seed coat through digestion means that the seed is ready to sprout when it gets deposited (along with a bit of fertilizer) by the disperser somewhere new in the environment. Yet other seeds require a brief exposure to fire to scarify the seed coat.\n\nIn species with thin seed coats, light may be able to penetrate into the dormant embryo. The embryo may then either use the presence of light or the absence of light to trigger its germination process. Small seeds with thin seed coats are likely to use light as a signal for germination. If these are buried shallowly enough for light to hit the seed, then its germination will initiate and before it runs out of reserves, its cotyledons will be doing photosynthesis. If the small seed is deeply buried it does not germinate; it has no idea how deep it is buried and may not have sufficient reserves on board to make it to the surface before they run out. Evolution favors shutting down germination in the dark for those species. For large-seeded species, the opposite may be true. There is an advantage to having your reserves buried before starting to germinate...otherwise the sprout just acts as a flag to say..."come and eat my nutritious seeds here on the surface." Evolution favors a large seed with lots of investment in storage to wait until it is buried before sending up its shoot. Such a seed will key in on darkness rather than light. In laboratory you will see an example of each of these kinds of evolutionary adaptations!\n\nIn yet other species, the embryo is fully developed when the seeds are dispersed. They need to be deposited in soil that possesses fungi that serve as host to the seed and seedling until the development is completed and the seedling is big enough to grow on its own. Trying to sprout many orchid seeds in common garden soil is futile...the required fungal hosts are not present...so leaving wild orchids where they naturally grow is the best idea.\n\nIn most species of wild plants the mother invests the seed with abscisic acid. This hormone makes the embryo dormant until environmental conditions and native enzymes permit the abscisic acid to be broken down inside the embryo. The enzyme required is present in the embryo in the fall, but it is inactive until activated by low temperature. About four weeks at 4°C is required to activate the enzyme and degrade all the abscisic acid in the embryo. This cold

Sounds like Malpitte (think I got the spelling right).  It a cactus seed that produces halucinations.  I've never used them, but I know that your friend was supposed to puke the seeds up a few minutes after taking them.  Who knows what kind of serious mind damage has been done.

Atchuete or Atsuete(Annatto)\n\nSeeds: Approximately 50 seeds grow inside the fruit. The seeds are about 5 mm in diameter and covered with red-orange pulp, which is the source of the orange-yellow dye. The embryo of the seed is poisonous. \n\nSee link:\nhttp://ecoport.org/ep?Plant=520&entityType=PL****&entityDisplayCategory=full\n\n\nHere is a picture:\nhttp://ca.store.yahoo.com/cranberrylane/herbs-herbs--spices---dried-flowers-annatto-seed.html
