Some plants produce spores and some produce seeds. The red dust which so disagreeably filled our eyes is composed of imperceptible spores, each atom containing a germ. Somebody managed to sneak a few of the dormant spores lying around outside the dome into him. VI (of X)-Great Britain and Ireland IV" by Various "The Best of the World's Classics, Restricted to Prose, Vol. It is the spore of the game we are tracking. Others have inert stages (like spores) that ensure their long-term survival during times without a host. Some defective mutant bacteria form more spores than the wild type in the presence of the wild type, but few or no spores in the absence of the wild type. When close to starvation, these bacteria develop fruiting bodies and form spores, whereby only a minority of the original bacterial cells turn into spores, while the others die.īiological Evolution and Statistical Physics The cap is the first part of the mushroom to develop, and then a long stem grows our from the spore at the bottom.Ĭomplex Networks from Simple Rewrite Systems Randomness and Multi-level Interactions in Biology Each spore therefore will become again an amoeba and a new cycle will start. Once found such a suitable environment, the slug will stop its search and transform itself into a stalk and a fruiting body where cells will be changed into spores to be released. īut there's a deadly spore in air, possibly making it's way to a produce garden near you. Stop the Ug99 Fungus Before Its Spores Bring Starvation. Spore suspensions are pure suspensions of viable spores from specific organisms of known resistance to various sterilization processes. IEEE Spectrum, the magazine of The Institute of Electrical and Electronics Engineers, is sponsoring a contest to build the ideal engineering life form-using Spore 's Creature Creator. The step-by-step process by which Spore 's creatures change does not have much to do with real evolution. You design it, making Spore 's most compelling attribute the way it blurs the line between creator and consumer. Game designer Will Wright speaks about his latest game SPORE at a promotion event in Singapore August 13, 2008. Spore has landed, and the long-awaited video game brings with it an evolutionary shift in how players interact with - and help create - games. The difference is that iTunes lets users de-authorize a computer?while Spore 's DRM doesn't. Spore 's DRM restrictions limited the number of times a user could activate the game, to curb piracy. Martika Spore, Arkansas City High School, Kan. In biology, an organic body of extremely minute size, and not subject to ordinary classification a sporozoid or zoöspore a living germ, as a seed of certain diseases.įiguratively, a germ a seed a source of being.
In zoology, the seed or germ of an organism, of minute size, and not of the morphological value of a cell, such as one of the microscopic bodies into which the substance of many protozoans is resolved in the process of reproduction by sporation a sporule a gemmule, as of a sponge. microspore, oöspore, protospore, pseudospore, pycnidiospore, stylospore, teleutospore, tetraspore, uredospore, zoöspore, zygospore, etc. See æcidiospore, ascospore, bispore, carpospore, chlamydospore, clinospore, macrospore. In the various divisions of cryptogams the spores are produced in many different ways and under various conditions. They are further peculiar in that they are motile, on which account they are called zoöspores. In certain plants, as some algæ and fungi, spores are produced which are for a time destitute of any cell-wall.
In those cases in which the spore is capable of germination immediately on the completion of its development, the cell-wall is a single delicate membrane consisting of cellulose but in those cases in which the spore must pass through a period of quiescence before germination, the wall is thick and may consist of two layers, an inner, the endospore, which is delicate and consists of cellulose, and an outer, the exo spore, which is thick and rigid, frequently dark-colored, and beset externally with spines or bosses, and which consists of cutin. In the majority of cases a spore consists of a nucleated mass of protoplasm, inclosing starch or oil as reserve nutritive material, surrounded by a cellwall. The name is given to all the reproductive bodies of cryptogamous plants, which are the analogues of the seeds of the higher or flowering plants, from which they further differ by having no embryo.
#Spore meaning free#
In botany, a single cell which becomes free and is capable of developing directly into a new morphologically and physiologically independent individual.
