| sporocyst | 1. <zoology> An asexual zooid, usually forming one of a series of larval forms in the agamic reproduction of various trematodes and other parasitic worms.

See Redia. 2. <zoology> Any protozoan when it becomes encysted produces germs by sporulation. Origin: Gr. Seed + bladder. Source: Websters Dictionary (01 Mar 1998) |
