Classification of ProtistaKingdom Protista is classified into the following:ProtozoaProtozoans are unicellular organisms. Historically, protozoans were called “animal” protists as they are heterotrophic, and showed animal-like behaviours.There are also parasitic protozoans which live in the cells of larger organisms. Most of the members do not have a predefined shape. For instance, an amoeba can change its shape indefinitely but a paramecium has a definite slipper-like shape. The most well-known examples of protozoans are amoeba, paramecium, euglena. Unlike other members of this group, euglena is a free-living protozoan that has chlorophyll, which means it can make its own food.The protozoans can be divided into four major groups:AMOEBOID protozoans – MOSTLY found in water bodies, either fresh or saline. They have pseudopodia (false feet) which help to change their shape and in capturing and engulfing food. E.g. AmoebaFlagellated protozoans – As the name suggests, the members of this group have flagella. They can be free-living as well as parasitic. E.g. EuglenaCiliated protozoans – They have cilia all over their body which help in LOCOMOTION as well as nutrition. They are ALWAYS aquatic. E.g. ParameciumSporozoans – These organisms are so-called because their life cycle has a spore-like stage. For example, the malarial parasite, Plasmodium.Explanation:please do follow me.
