Sporozoans are motile

Detailed explanation-1: -Sporozoans are non-motile, unicellular protists, usually parasites. These protozoans are also called intracellular parasites.
Detailed explanation-2: -Locomotion. 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-3: -Unlike the crawling movement of amoebae and vertebrate fibroblasts, sporozoon protozoa are characterized by a ‘gliding movement’ in which no obvious changes occur in cell shape.
Detailed explanation-4: -Sporozoans are characterized by being one-celled, non-motile, parasitic, and spore-forming. Most of them have an alternation of sexual and asexual stages in their life cycle. An example of sporozoan is the Plasmodium falciparum, which is the causative agent of malaria.
