Malarial parasite is injected into man as__________?

Correct answer: A. sporozoites

  • A. sporozoites
  • B. merozoites
  • C. zygote
  • D. none of these

Explanation

The female Anopheles mosquito injects Plasmodium sporozoites into human blood during a bite, and these first travel to liver cells. Merozoites are released later from infected liver or red blood cells, so students may choose them by confusing the next stage with the injected stage.
