sporocyst

[′spȯr·ə‚sist]
(botany)

(invertebrate zoology)
A resistant envelope containing an encysted sporozoan.
An encysted sporozoan.
The first reproductive form of a digenetic trematode in which rediae develop.

Sporocyst

 

(l) A stage in the development of some unicellular animals of the class Sporozoa, for example, coccidians and grega-rines. Embryos, or sporozoites, develop in sporocysts. In coccidians sporocysts develop as a result of division of the zygote into several mononuclear cells. The entire zygote in gregarines is converted into sporocyst.

(2) The first parthenogenetic generation in trematodes whose larvae are miracidia. In most trematodes the miracidia are transformed into sporocysts as soon as they penetrate the tissues of the intermediate host, a gastropod. A sporocyst is saccular or tubular in shape. In some species sporocysts have excretory organs, or protonephridia. The second parthenogenetic generation, the redia, usually develops from embryonic cells in the body cavity of the sporocyst. Only in a few species, for example, the lancet fluke, does another generation of sporocysts form from the embryonic cells.
