Locomotion of protozoa is by ___, or by means of pseudopodia, flagella or cilia.
Explanation
Protozoa can move by gliding, which refers to their ability to move smoothly over surfaces. This type of locomotion is achieved through the secretion of a slimy substance that allows them to slide or glide along. Unlike other forms of locomotion such as pseudopodia, flagella, or cilia, gliding does not involve the use of appendages or extensions. Instead, it relies on the secretion and movement of this slimy substance to facilitate movement.Rate this question:
