a) Plasmodium falciparum causes malignant malaria which is the most serious disease and can even be fatal.

b)When a female Anopheles mosquito bites an infected person, these parasites enter the mosquito’s body and undergo further development. The parasites multiply within them to form sporozoites that are stored in their salivary glands. When these mosquitoes bite a human, the sporozoites are introduced into his/ her body, and the parasites initially multiply within the liver cells and then attack the RBC’s resulting in their rupture.

c) Plasmodium enters the human body as sporozoites (infectious form) through the bite of infected female Anopheles mosquito. The parasites initially multiply within the liver cells and then attack the red blood cells (RBCs) resulting in their rupture. The rupture of RBCs is associated with the release of a toxic substance, hemozoin, which is responsible for the chill and high fever recurring every three to four days.
