Biology Question on Kingdom Protista
Plasmodium, the malarial parasite, belongs to class
A
sarcodina
B
ciliata
C
sporozoa
D
dinophyceae.
Answer
sporozoa
Explanation
Solution
These protozoans are adapted to parasitic mode of life. All of them are endoparasites. Locomotory organelles (cilia, flagella, pseudopodia, etc.) are absent. Organelles connected with ingestion are absent. Nutrition is parasitic (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).
