Propagator


Definition:

  • (20) In cells treated with ion across membranes, tip to base propagation was seen only in the presence of EGTA; when calcium was added the majority of organisms propagated waves from base to tip.

Seed


Definition:

  • (pl. ) of Seed
  • (n.) A ripened ovule, consisting of an embryo with one or more integuments, or coverings; as, an apple seed; a currant seed. By germination it produces a new plant.

  • (n.) That from which anything springs; first principle; original; source; as, the seeds of virtue or vice.
  • (n.) The principle of production.
  • (n.) Progeny; offspring; children; descendants; as, the seed of Abraham; the seed of David.
  • (n.) Race; generation; birth.
