A Cell

Explanation;

A Cell is a rectangular box that occurs at the  intersection of a vertical column and a row in Excel application. As a result, it can be identified by coordinates referencing the letter of the vertical column and the number of the horizontal row whose intersection it was created at. For instance, if a Vertical column C created a cell at an intersection with Horizontal row 68, the cell would be called C68.

Cells can only be used to store a piece of data at a time but can store a variety of data including formulas, numericals, and alphabets/text.
