Motile
An organism is called motile if it can move on its own. Most organisms are motile. Organisms that cannot move themselves are called sessile.

Cell division. All cells can be considered motile for having the ability to divide into two new daughter cells.
Eukaryotic cytoskeletons induce cells to move through liquid and over surfaces, divide into new cells, and the cytoskeleton guides the transport of organelles within the cell. This video captures stained cytoskeletons from the cross section of a leaf of Arabidopsis thaliana.
The shoots of plants move by growing towards light. This is known as positive phototropism. The roots grow away from light. This is known as negative phototropism.
Monocytes and macrophages of the immune system engulf Bacteria by extending their pseudopodia. Note that this cartoon is not an accurate representation of phagocytosis.
Motility at the sub-cellular level. This depicts translation - a motile nanoscale molecular process using protein dynamics.
