Select an option to attempt
Correct Answer: Option A
Explanation
Plasmodium sporozoite location in mosquito:Life cycle of Plasmodium (malaria parasite) in the Anopheles mosquito vector:1. When a mosquito takes a blood meal from an infected human, it ingests gametocytes.2. Gametocytes mature into gametes → fertilisation → ookinete → oocyst (in midgut wall).3. Oocysts rupture → release sporozoites → sporozoites MIGRATE to the SALIVARY GLANDS.4. When the infected mosquito bites a new human, sporozoites are INJECTED with saliva into the bloodstream.5. Sporozoites travel to the LIVER (exoerythrocytic stage), infect hepatocytes, multiply, and later release merozoites into the blood.Conclusion: Sporozoites are found in the SALIVARY GLANDS of the Anopheles mosquito.Answer: Sporozoites in salivary glands of infected Anopheles mosquito.
