From Wikipedia, the free encyclopedia
A seed [siːd] (help·info) is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes the process of reproduction in seed plants (started with the development of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule.
Seeds have been an important development in the reproduction and spread of flowering plants, relative to more primitive plants like mosses, ferns and liverworts, which do not have seeds and use other means to propagate themselves. This can be seen by the success of seed plants (both gymnosperms and angiosperms) in dominating biological niches on land, from forests to grasslands both in hot and cold climates.
The term seed also has a general meaning that predates the above — anything that can be sown i.e. "seed" potatoes, "seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds", what is sown is the seed enclosed in a shell or hull, and the potato is a tuber.
Seed size and seed set
Seeds are very diverse in size. The dust-like orchid seeds are the smallest with about one million seeds per gram. Embryotic seeds have immature embryos and no significant energy reserves. They are myco-heterotrophs, depending on mycorrhizal fungi for nutrition during germination and the early growth of the seedling, in fact some terrestrial Orchid seedlings spend the first few years of their life deriving energy from the fungus and do not produce green leaves. At over 20 kg, the largest seed is the coco de mer. Plants that produce smaller seeds can generate many more seeds while plants with larger seeds invest more resources into those seeds and normally produce fewer seeds. Small seeds are quicker to ripen and can be dispersed sooner, so fall blooming plants often have small seeds. Many annual plants produce great quantities of smaller seeds; this helps to ensure that at least a few will end in a favorable place for growth. Herbaceous perennials and woody plants often have larger seeds, they can produce seeds over many years, and larger seeds have more energy reserves for germination and seedling growth and produce larger, more established seedlings.

Hello ralf. Nice capture of this seed in good clear details. Useful notes too. Well done and best regards. Jusni

A very interesting shot and I must say the way I've never seen a Jalapeño before. I only see it fresh or prepared and ready for human consumption, just the way I like it.
Actually I never thought I would look at a photo of a seed like this on TrekNature and do a critique on it, but heck it is nature and it deserves to be captured, displayed, described, and discussed and I am pleased that people like you look at that side of nature as well. Good for you.
A good capture and the diagonal composition worked well. The flash control was well executed and provided good lighting and the colour tones are fine. The dark BG makes the seed pod stand out and all details are clearly visible.
Well done and TFS.
PS. Thanks for the good notes too.

very original shot. Good contrast between black BG and the seed. You have control the light quite good. Good idea to put it in a diagonal. Good POV an details. Nice work!
have a nice day
