spore Scientific  
/ 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.

  4. See endospore


spore Cultural  
  1. A reproductive cell or group of cells, produced by some plants, that is capable of developing into an adult plant without combining with another reproductive cell. Plants also produce sperm cells. The spores of nonflowering plants are analogous to the seeds of flowering plants. (See asexual reproduction; compare sexual reproduction.) Fungi and algae typically reproduce by means of spores that are carried by the wind or some other agency to a new location for growth.

Etymology

Origin of spore

1830–40; < New Latin spora < Greek sporá sowing, seed, akin to speírein to sow; sperm 1

Explanation

Spores are the seed-like cells that help some kinds of plants and bacteria to reproduce. Ferns and mosses reproduce using spores. Many plants reproduce by means of flowers, which make seeds. Most plants that don't produce seeds use spores to spread themselves around. Spores are microscopic, and plants like mosses and ferns make huge quantities of spores, which are blown around by the wind so they can grow in new places. Spore comes from the Greek spora, "seed-time" or "a sowing."
