What's the difference between sporocyst and trematode?
Sporocyst
Definition:
(n.) An asexual zooid, usually forming one of a series of larval forms in the agamic reproduction of various trematodes and other parasitic worms. The sporocyst generally develops from an egg, but in its turn produces other larvae by internal budding, or by the subdivision of a part or all of its contents into a number of minute germs. See Redia.
(n.) Any protozoan when it becomes encysted produces germs by sporulation.

Trematode
Definition:
(n.) One of the Trematodea. Also used adjectively.
Example Sentences:
(1) The adults of the trematode occurring in the nasal sinuses and posterior nasal passage of the dolphins are considered as practically harmless for the host but thier eggs, aspirated deep into the bronchial tree, may initiate a foreign-body of inflammatory reaction in the lungs and continuous aspiration of such eggs may provoke a chronic pneumonia condition.
