Vedclass · Answer

(A-D) 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.
