Differentiate Brownian movement from true motility Methods: Place the prepared specimen under the microscope. Observe for Brownian movement (Non-motile organisms are tiny particles in suspension. Also, they exhibit movement characterized by an oscillating, quivering motion.) Or and True motility (Motility of microorganisms is an independent, true movement of translation brought about by organs of locomotion or by gliding.) With the presented specimen, observe and determine whether the specimen shows true motility or brownian movement.
