Answer

A malaria-infected female Anopheles mosquito inoculates sporozoites into the human host which infects the liver cells and releases merozoites. It will then multiply in the liver through asexual multiplication. These merozoites infect the red blood cell. THe gemtocytes will be ingested by the Anopheles mosquito during blood meal and will undergo sporogonic cycle. Inoculation of sporozoites in new human host prolongs malarial life cycle.
