The sporozoites that cause infection when a female Anopheles mosquito bites a person, are formed in:
a. liver of the person
b. RBCs of mosquito
c. salivary glands of mosquito
d. gut of mosquito
The answer is the option (d) intestine of mosquito
Explanation: The sporozoites, which are the infective stage of the malaria-causing parasite (Plasmodium), are produced in the mosquito's gut and then migrate to its salivary glands. When the female Anopheles mosquito bites a person, these sporozoites are transmitted into the human bloodstream, initiating the infection.
