During malaria transmission, what form of the parasite is introduced into the human bloodstream by a mosquito bite?

Explanation

The malaria parasite is transmitted to humans through the bite of an infected mosquito in the form of sporozoites. These sporozoites enter the bloodstream and initiate infection. Merozoites, hypnozoites, and gametocytes are different stages of the parasite's life cycle but are not directly transmitted by mosquito bites.
