In this article we will discuss about the characters and examples of Sporozoans. Characters of Sporozoans: (i) All sporozoans are endoparasites. (ii) Some sporozoans such as Eimeria cause severe diseases like coccidiosis in the birds, (iii) Locomotory organelles (cilia, flagella, pseudopodia, etc.) are absent. (iv) Nutrition is parasitic (absorptive). Phagotrophy is rare. (v) The body is covered with an elastic [...]
The following points highlight the eight characters of amoeboid protozoans. (i) Amoeboid Protozoans develop pseudopodia which are temporary protoplasmic outgrowths. They are of four types— lobo podia (broad and blunt), filo podia (slender, unsupported, independent), axopodia (slender with axial support) and reticuiopodia (slender, reticulate). (ii) Pseudopodia are used for locomotion and engulfing food articles. (iii) Sarcodines are mostly free living, [...]
The following points highlight the twelve characters of ciliated protozoans. (i) Ciliates are protozoan protists which develop a number of cilia during a part or whole of the life cycle. (ii) Cilia are used for locomotion and driving food. (iii) There is a high degree of morphological and physiological specialization. (iv) Most ciliates are free living individuals in fresh and [...]
