Q111 (CDS-II/2026) Science & Technology › Biotechnology & Health

Consider the following statements associated with Malaria :
1. Only the female Anopheles mosquitoes take human blood for reproduction
2. Plasmodium can pass across the placenta from mother to foetus
Which of the statements given above is/are correct ?

Result
Your answer: —  ·  Correct: C

Explanation

Both statements are correct.

  • Statement 1: Male mosquitoes feed exclusively on nectar and plant juices for energy. Only female Anopheles mosquitoes bite humans because they require a blood meal to obtain specific proteins and iron necessary for the production and development of their eggs.
  • Statement 2: Malaria can be transmitted from a pregnant woman to her unborn baby, a condition known as congenital malaria. The Plasmodium parasite can cross the placental barrier during pregnancy or infect the infant during childbirth through maternal-fetal blood exchange.

Malaria is a life-threatening disease caused by Plasmodium parasites. While the primary mode of transmission is the bite of an infected female Anopheles mosquito, it can also spread through blood transfusions, organ transplants, or the shared use of needles contaminated with blood.
