C.

Gut of female Anopheles

When female Anopheles, sucks the blood of an infected person, the gametocytes of plasmodium are picked up by the mosquito. Now sexual reproduction of Plasmodium occurs inside mosquito. The outer envelope of gametocyte is dissolved and its contents are liberated into the cavity of gut. These content undergo gametogony, i.e., formation of microgametes and macroagamete. The nuclei of both fuse and a synkaryon or zygote is formed. This zygote is motionless and spherical for sometime and vermiform very soon. Now, it is called vermicule or ookinete. Ookinete pierces the stomach wall and forms a cyst(oocyst) on its outer surface which has about 1000 sporozoites. The latter pass into salivary glands of the mosquito.
