Understand the life cycle of Plasmodium, the parasite responsible for malaria. It involves several stages, including sporozoites, merozoites, and gametocytes.
Identify the role of sporozoites: These are the infective stage of Plasmodium that are injected into the human bloodstream by an infected mosquito.
Recognize that once sporozoites enter the human body, they travel to the liver cells where they undergo a transformation.
Learn that in the liver, sporozoites develop into merozoites. These merozoites are then released into the bloodstream where they infect red blood cells.
Review the options provided and match the stages correctly: Sporozoites are injected by the mosquito and become merozoites in the liver, which then infect red blood cells.
