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.

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.
