The Brownian movement is a result from random motion of water molecules that bombard the bacteria and causes the bacteria to move. True motility involves the 3 modes of motility and self propulsion does so as well.
Particles must be extremely small to demonstrate Brownian movement because their tiny size allows them to be significantly affected by the random collisions with the much larger and more numerous molecules of the surrounding fluid. This random motion becomes evident only when the particle is small enough that these collisions impart noticeable displacement. Larger particles would experience reduced relative motion, as their inertia would dominate, masking the effects of these random collisions. Thus, the scale of the particles is crucial for observing the erratic, jittery movement characteristic of Brownian motion.
These particles are called atoms.

Matter.
Matter is made up of tiny particles called atoms and molecules. These particles come together to form different substances and materials in our physical world. The properties and behavior of matter are determined by the interactions between these particles.
Brownian motion is the random movement of particles suspended in a fluid as they collide with other particles. A common example is the movement of pollen grains in water. You can observe Brownian motion in action by observing the random movement of tiny particles under a microscope.

Brownian motion provided evidence for the kinetic model of matter by observing the random movement of particles in a fluid. This motion was consistent with the idea that matter is composed of tiny particles in constant motion, supporting the kinetic theory. By studying the erratic movement of particles under a microscope, scientists were able to indirectly observe the existence of atoms and molecules.
Brownian motion, named after botanist Robert Brown. The motion is also known as pedesis which translates from Greek as 'leaping'.
If tiny particles like pollen are added to clear water and observed through a micrscope they will be seen to move about randomly. This was an early clue to the fact that matter is made of individual molecules which, in the case of liquids and gases, move about to cause the Brownian motion of the particles first observed by botanist Robert Brown.

Particles can be kept suspended in a fluid through mechanisms such as Brownian motion, turbulence, and electrostatic repulsion between particles. These forces prevent the particles from settling to the bottom of the container.
