spore (spôr, sp r)n.1. A small, usually single-celled reproductive body that is highly resistant to desiccation and heat and is capable of growing into a new organism, produced especially by certain bacteria, fungi, algae, and nonflowering plants. 2. A dormant nonreproductive body formed by certain bacteria in response to adverse environmental conditions. intr.v. spored, spor·ing, spores To produce spores.
[Greek spor , seed; see sper- in Indo-European roots.]

spore Noun
a reproductive body, produced by nonflowering plants and bacteria, that develops into a new individual [Greek spora a sowing]
spore (spôr)1. A usually one-celled reproductive body that can grow into a new organism without uniting with another cell. Spores are haploid (having only a single set of chromosomes). Fungi, algae, seedless plants, and certain protozoans reproduce asexually by spores. Plant spores that are dispersed by the wind have walls containing sporopollenin. 3. A similar one-celled body in seed-bearing plants; the macrospore or microspore. The macrospore of seed-bearing plants develops into a female gametophyte or megagametophyte, which is contained within the ovule and eventually produces the egg cells. (The megagametophyte is also called the embryo sac in angiosperms.) The microspore of seed-bearing plants develops into the male microgametophyte or pollen grain. See endospore. |
