Given below are two statements.
Statement I - Sporozoites ofPlasmodiumreproduce asexually to produce merozoites.
Statement II - Zygote ofPlasmodiumwithin the erythrocytes transforms into oocyst.
In the light of above statements, choose the correct option given below:
Options:
Answer:
Solution:
Statement I is correct because sporozoites ofPlasmodiumenter the human body through the bite of an infected femaleAnophelesmosquito, reach the liver cells, and reproduce asexually (schizogony) to produce a large number of merozoites.
Statement II is incorrect because the zygote ofPlasmodiumis formed in the stomach (midgut) of the femaleAnophelesmosquito, not in human erythrocytes. The gametocytes are taken up by the mosquito during a blood meal, and fertilization occurs in its gut. The resulting zygote develops into a motile ookinete, which penetrates the gut wall and transforms into an oocyst.
Answer: Statement I is correct but statement II is incorrect.
