Identify the correct sequence of steps involved in the life cycle of Plasmodium.
A. Sporozoites reach the liver through blood
B. Parasites reproduce asexually in blood cells
C. Parasites reproduce asexually in liver cells
D. Fertilization takes place in mosquito’s gut
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A, C, B, D
(A) Sporozoites reach the liver through blood — this comes first. The infected female Anopheles mosquito bites a person and passes sporozoites, the infective form, into the blood. They travel to the liver.
(C) Parasites reproduce asexually in liver cells — this comes second. In the liver cells the parasites multiply.
(B) Parasites reproduce asexually in blood cells — this comes third. The parasites then attack the red blood cells and multiply in them. The cells burst and release the parasites, which causes the fever.
(D) Fertilization takes place in mosquito’s gut — this comes last. A mosquito that bites the infected person takes in the sexual forms of the parasite. They fuse in the mosquito’s gut, and the parasite develops further there.
