Spore, a reproductive detached cell of a cryptogamous or so-called flowerless plant, not containing an embryo as does a seed. Spores are the reproductive bodies of ferns, mosses, club-mosses, liverworts, fungi, and similar plants. They are of interest to the plant- grower mostly as the means of propagating ferns. For description, see Ferns and Fungi; also the articles on Mildew, Rust, and Smut. For propagation by spores, see the discussion under Ferns.
