Malaria is caused by the biting of female Anopheles mosquito to the healthy human being releasing Plasmodium, which lives in an infectious form (sporozoite). 1. First, it undergoes asexual reproduction when the parasites burst the liver cells by multiplying itself that are released into the blood.

Study a part of the life cycle of malarial parasite given below. Answer the questions that follow: (a) Mention the roles of ' A ' in the life cycle of the malarial parasite. (b) Name the event ' C ' and the organ where this event occurs. (c) Identify the organ ' B ' and name the cells being released from it.
I. The merozoites are initially formed in the liver cells and attack the RBCs upon their release. II. Rupturing of RBCs releases hemozoin into the blood. III. The Plasmodium parasite has a single host. IV. When a female Anopheles mosquito bites a malaria patient, it picks up the sporozoites from the human blood. View Solution.
Anopheles mosquito is known to be the carriers or vectors for malarial parasites Plasmodium. These malarial parasites complete its life cycle in two hosts, first when it enters the human body as sporozoites from the body of mosquito which grows as merozoites in the human blood stream and moves on as gametocytes back to the body of the mosquito.
That is, the first life stage of Plasmodium (stage of infection). The next stage in malaria life cycle is the one of asexual reproduction that is divided into different phases the pre- erythrocytic (or exoerythrocytic) and the erythrocytic phase. Within 30- 60 minutes after the parasites inoculation, sporozoites find their way through blood ...
Question. Describe the asexual and sexual phase of life cycle of Plasmodium that causes malaria in humans. Solution. Verified by Toppr. Plasmodium completes its life cycle in two phases, asexual phase in human blood and sexual phase in mosquitoes. The complete life cycle is described by the given figure.
In malaria, the life cycle of Plasmodium can be divided into two distinct phases i.e., the asexual cycle in humans and the sexual cycle in mosquitoes. To begin the asexual cycle in humans, an infected female Anopheles mosquito injects sporozoites into the new human host and enters liver (exo-erythrocytic cycle).
Fever and Chills, general sensation of uneasiness, migraine, Nausea and retching, Abdominal torment, Muscle or joint torment, Fatigue, Rapid breathing, fast pulse, Cough are some more symptoms found in the start of malaria or at a specific phase of malaria. It is helpful to recognize the presence of the microorganism in the body.
Life cycle of Plasmodium • The sporozoites of Plasmodium are infected into the human blood when its vector, a female Anopheles mosquito bites the person. • These sporozoites then enter into the liver through blood circulation.
