    The sporozoites that cause infection when a female Anopheles mosquito bites a human being are developed in

    Study carefully the following stages of life cycle of malarial parasite i.e., Plasmodium. Arrange these stages in the correct sequence and select the correct answer. 1. Sporozoites leave the blood stream and enter the liver cells of man. 2. Sporozoites present in the salivary glands of female Anopheles mosquito are injected into the blood stream of man. 3. The parasite reproduces asexually in RRCs, resulting in bursting of RRCs and causing the cycles of fever, released parasites infect new RRCs. 4. The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells. 5. Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RRCs. 6. Female Anopheles mosquito takes up the gametocytes with blood meal of an infected person. 7. Mature infective stage of the parasite i.e., sporozoites escape from intestine and migrate to the mosquito's salivary glands. 8. Fertilisation and developmental stages of the parasite take place in mosquito's stomach.

    Female Anopheles mosquito is the vector of:

    The sporozoites that cause infection, when a female Anopheles mosquito bites a person, are formed in

    Assertion : Plasmodium causes disease in female Anopheles mosquitoes. Reason : Female Anopheles mosquitoes feel on human blood.
