Protozoans are divided into four main groups based on their mode of locomotion and other characteristics. Sporozoa are non - motile parasites. Ciliophora move using cilia. Sarcodina move by pseudopodia. Mastigophora move with flagella. Pseudopodia is a mode of movement, not a group. Trypanosoma is a genus within the mastigophora group. Entamoeba is a genus within the sarcodina group.

sporozoa, cilliophora, sarcodina, mastigophora
