Question 2

Malaria cycle

Answer 2

Gametocytes infect mosquito. When mosquito sucks blood with gametocytes it turns into sporozoites in salivary glands.
Sporozoites are passed onto humans when Mosquitos bite us. These sporozoites go to the liver where they turn into merozoites.
Merozoites are released from the liver into the blood. Where they enter red blood cells. Some of these then into schizonts.
Schizonts burst the red blood cells releasing more merozoites. This coincidences with the fever.
Some merozoites reproduce into female gametocytes which are passed onto the mosquito when it bites.
