Vedclass · Answer

(A) Protozoans are heterotrophic organisms that live as predators or parasites and are believed to be primitive relatives of animals. They are classified into four major groups based on their locomotory organelles:$1$. Amoeboid protozoans: These organisms live in fresh water, sea water, or moist soil. They move and capture their prey by putting out pseudopodia (false feet), e.g., $Amoeba$.$2$. Flagellated protozoans: These members are either free-living or parasitic. They possess flagella for locomotion. Parasitic forms cause diseases such as sleeping sickness, e.g., $Trypanosoma$.$3$. Ciliated protozoans: These are aquatic, actively moving organisms because of the presence of thousands of cilia. They have a cavity (gullet) that opens to the outside of the cell surface, e.g., $Paramecium$.$4$. Sporozoans: This group includes organisms that have an infectious spore-like stage in their life cycle. The most notorious is $Plasmodium$ (malarial parasite) which causes malaria in humans.

Describe the characteristic features of the group Protozoa under Kingdom Protista and explain its four major groups.
