A person suffering from a disease caused by Plasmodium, experiences recurring chill and fever at the time when

  1. the parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs.
  2. the trophozoites reach maximum growth and give out certain toxins
  3. the sporozoites released from RBCs are being rapidly killed and broken down inside spleen
  4. the microgametocytes and megagametocytes are being destroyed by the WBCs.

Answer

(1) the parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs.

Solution

As per NCERT, Plasmodium multiplies asexually in the RBCs and bursts them.

⇒ The rupture of RBCs is associated with the release of a toxic substance, haemozoin, which is responsible for the chill and high fever recurring every three to four days.

⇒ The released parasites (merozoites) enter fresh RBCs.
