Hi Jacob, 

• The Plasmodium undergoes asexual reproduction when the parasites burst the liver cells by multiplying itself and are released into the blood.
• Plasmodium bursts the RBCs by entering the RBCs, multiplying by the means of asexual reproduction.
• Along with the bursting of RBCs, a toxic element called haemozoin is released which causes chills in the body of the human being.
• Gametocytes multiply forming from the sporozoites that multiply sexually.
• Gametocytes are introduced into the mosquito when the female Anopheles mosquito bites the diseased person.
• Gametocytes again form sporozoites by fertilising inside the intestine of the mosquito.
• These sporozoites are stored in the salivary glands of mosquito and are released when the healthy person is bitten by this mosquito.
