Determination

Explanation:

Cell determination is one of the fundamental processes that result in the development of the form of an organism. Cell determination refers to a series of molecular events that alter the activities of certain genes in a particular way. These events finally make a cell to progressively commit to a particular differentiation pathway.

The events of cell determination may not cause any immediate changes in the structure and function of the cells but regulate them eventually. Once the cell determination events make a cell to differentiate in a particular way, the cell is specialized to carry out specific functions which means that its development fate is sealed.
