Detailed explanation-1: -Mastigophora or Flagellated protozoans: Sarcodina or Amoeboids: Sporozoa or Sporozoans: Ciliophora or Ciliated protozoans:

Detailed explanation-2: -Protozoa can be divided into four phyla based on their locomotion: Mastigophora, Sarcodina, Ciliophora, and Sporozoa. Members of the phylum Mastigophora move about by using one or more whiplike flagella.

Detailed explanation-3: -Protozoa move in the environment in three different ways: ameboid movement, flagella, and cilia. The ameboid movement is typical of ameboid protozoa (see below) and some other forms. Movement is achieved by cytoplasmic protrusions known as pseudopodia.

Detailed explanation-4: -Historically protozoa were divided into four major groups: the ameba, the flagellates, the ciliates, and the sporozoa. The distinguishing features between the groups was based on motility (i.e., ameboid, flagella, cilia).

Detailed explanation-5: -Protozoans exhibit diverse modes of locomotion across the various groups, but the modes of locomotion can be broadly divided into flagellar, ciliary, and amoeboid movement. Only the ciliates among the three major motility groups of protozoans, however, represent a truly monophyletic group (or single evolutionary line).
