spore

Definitions

  • WordNet 3.6
    • n spore a small usually single-celled asexual reproductive body produced by many nonflowering plants and fungi and some bacteria and protozoans and that are capable of developing into a new individual without sexual fusion "a sexual spore is formed after the fusion of gametes"

  • Interesting fact: The giant puffball, lycoperdon giganteum, produces 7,000,000,000,000 spores, each of which could grow into a puffball a foot in diameter and collectively cover an area of 280,000 square mile, greater than the size of Texas. Fortunately, only one of the spores actually becomes a puffball, and all the others die.
    • Spore (Biol) A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc.
    • Spore (Bot) An embryo sac or embryonal vesicle in the ovules of flowering plants.
    • Spore (Bot) One of the minute grains in flowerless plants, which are analogous to seeds, as serving to reproduce the species.
    • Spore (Biol) One of the parts formed by fission in certain Protozoa. See Spore formation, belw.

    • n spore A. Middle English form of spur.
    • n spore In botany, a single cell which becomes free and is capable of developing directly into a new morphologically and physiologically independent individual. 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. 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. 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 certain plants, as some algæ and fungi, spores are produced which are for a time destitute of any cell-wall. They are further peculiar in that they are motile, on which account they are called zoöspores. In the various divisions of cryptogams the spores are produced in many different ways and under various conditions. See æcidiospore, ascospore, bispore, carpospore, chlamydospore, clinospore, macrospore. microspore, oöspore, protospore, pseudospore, pycnidiospore, stylospore, teleutospore, tetraspore, uredospore, zoöspore, zygospore, etc.
    • n spore 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.
    • n spore 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.
    • n spore Figuratively, a germ; a seed; a source of being.

    • n Spore spōr the reproductive body in flowerless plants like the fern, analogous to the seeds of ordinary flowering plants, but containing no embryo: a germ, a seed, a source of being generally

Great projects in his brain,
Until He drops the fungus spore
That smears them out again.
