Where will you look for the sporozoites of the malarial parasite?
Correct answer: A. Saliva of infected female Anopheles mosquito
- A. Saliva of infected female Anopheles mosquito
- B. Red blood corpuscles of human suffering from malaria
- C. Spleen of infected humans
- D. Salivary glands of freshy moulted female Anopheles mosquito
Explanation
Sporozoites represent the infective forms of malarial parasites. A healthy person acquires infection, when a female Anopheles mosquito, containing sporozoites, bites the person for sucking his blood. The mosquito punctures the host's skin by its proboscis and first introduces some saliva into the bloodstream. Along with saliva, thousands of sporozoites are inoculated in the host. The motile zygote then undergoes further development in the mosquito's gut to produce sporozoites, which migrate to the mosquito's salivary glands.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
