Some of the events occur during life cycle of Plasmodium are given below. Identify the correct statement.
1 The sporozoites reproduce sexually in liver cells.
2 The gametocytes develop in RBC.
3 Female mosquito take up sporozoites with blood meal.
4 When mosquito bites a man, gametocytes are injected.
Explanation:
The parasites (Plasmodium) have evolved to infect a wide range of vertebrate hosts including reptiles, birds and a variety of mammals from rodents to primates. - The most commonly used animal models in malaria research are mice, birds, and non-human primates with each selected for a variety of reason including availability case of handing, and evolutionary relationship to human. - The gametocytes of Plasmodium falciparum responsible for the transmission of this malaria parasite from human to mosquitoes accumulate and mature preferentially in the bone marrow.

4 nucleo-cytoplasmic inheritance
Explanation:
Kappa particles were discovered by Sonneborn. - It is found in Paramecium aurelia and it produces toxins that kills many animals. - It shows cytoplasmic inheritance. Nuclear inheritance occurs due to gene present on the chromosome. - Kappa particle is denoted by ' $K$ '.
