Solution:
Human infection (transmission) occurs when a female mosquito inoculates thesporozoitesofPlasmodiumfrom its salivary gland into the blood of man. The sporozoites invade the cells of the liver and reproduce through multiple fission or sporulation (asexual reproduction) calledpre-erythrocytic, exoerythrocytic, or intrahepatic schizogony or merogony. Each sporozoite produces daughtermerozoites.These merozoites are released into the bloodstream through the infected liver cell. Once the merozoites are in the blood, they quickly invade RBCs and becometrophozoites.
