Q. Choose the correct statements for Malaria.

1. Malaria is a protozoan infection
2. It is caused by P. falciparum, P. vivax, P. malariae and P. ovale
3. It is caused by the female Anopheles mosquito
4. It is spread by the female Anopheles mosquito

Q. Which of the following is a parasitic protozoan?

1. Amoeba
2. Plasmodium
3. Paramecium
4. Euglena

Q. Assertion :Within liver, cell cycle is called as pre-erythrocyctic schizogony, as sporozoites of malarial parasite actively feed upon its cytoplasm and grow into large and spherical, adult like forms, called as cryptozoites. Reason: Cryptozoites divide into about numerous minute cryptomerozoites by a special multiple fission, called as schizogony.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
