Solution and Explanation

Gametocytes of Plasmodium, consumed with human blood, mature into gametes within the mosquito's digestive tract. Fertilization yields a zygote, which transforms into an ookinete and subsequently an oocyst. The oocyst then liberates sporozoites, which travel to the mosquito's salivary glands, poised to infect a new human host.
