Question

Plasmodium , the malarial parasite, belongs to class ____________
A. Sarcodina
B. Ciliata
C. Sporozoa
D. Dinophyceae

Answer 1

Plasmodium is a genus of obligate parasitic unicellular eukaryotes that live in vertebrates and insects. Plasmodium species have life cycles that include development in a blood-feeding insect host before injecting parasites into a vertebrate host during a blood meal. Parasites develop within a vertebrate body tissue (usually the liver) before infecting red blood cells in the bloodstream.

Complete answer:
These protozoans have evolved to live in a parasitic state. They're all endoparasites. There are no locomotory organelles present. Ingestion-related organelles are missing. Nutrition has a parasitic nature (absorptive). Syngamy is a method of sexual reproduction. It is followed by the development of spores, hence the name sporozoa.

As a result, the right response is (C) 'Sporozoa.'

These protozoans have evolved to live in a parasitic state. They're all endoparasites. Cilia, flagella, pseudopodia, and other locomotory organelles are missing. Ingestion-related organelles are missing. Nutrition has a parasitic nature (absorptive).
Sexual reproduction takes place through syngamy. It is followed by spore formation, hence sporozoans. Life cycle consists of two distinct asexual and sexual phases. They may be passed in one (monogenetic) or two different hosts (digenetic).

Plasmodium belongs to the Apicomplexa phylum, a broad group of parasitic eukaryotes. Plasmodium belongs to the order Haemosporida and family Plasmodiidae. Plasmodium has been divided into 14 subgenera based on parasite morphology and host range. There are over 200 species of Plasmodium.

Note:-
Sporozoites from a mosquito's salivary gland are the human-infective stage. The sporozoites multiply in the liver and eventually become merozoites. These merozoites infect red blood cells (RBCs) and create trophozoites, schizonts, and gametocytes, which cause malaria symptoms.
