If you want to make a cell stand out, you can make the text bold, change the font and font size, make the cell italic, change the foreground or background color, and use borders.

In Excel 2003, it was called splitting. To bring them back together it is called merging.
Clicking a cell will select it. You can select more by dragging out over them.
Depending on what you mean, it could be a range, which is a group of cells in Excel, that can be referenced in a formula as a block, but they are not a single cell then. You could be referring to cells that have been merged, in which case Excel treats them as a single cell.
At any moment in time, at least one cell has to be selected in Excel. It is known as the active cell. There has to be a focal point so that data or formulas can be typed in. Even when more than one cell is selected, there is only one active cell. Which cell is the active cell can be changed at any time, but there always has to be an active cell. If there isn't then, before you do anything, you would have to make a cell active. Cells are fundamental to Excel so there has to be an active cell at all times.
If you make two or more cells into one cell, that is called merging the cells.
If you select one cell, it will be active. However, if you select multiple cells at once, only one can be the active cell. That is usually the cell you select first.
In Excel's Goal Seek feature, the "Set Cell" field represents the formula element that you want to solve or target a specific value for. This is typically the cell containing a formula that depends on one or more input variables. The "By Changing Cell" field is where you specify the input variable that Excel will adjust to achieve the desired outcome in the "Set Cell."
It is called Merging in Microsoft Excel. There is one issue though, you gotta be careful when merging as either of the cell value could get deleted.
This question is not clear in reference to Excel. My best guess what you are asking is how to add text to a column in Excel. You select the cell you want and enter the data you want, then go to the next cell and continue. NOTE: If this does not answer your question, please ask a more specific question.
You can merge more than one cell into one cell and then have it across more than one column. The text would still be centred in one cell, but it is a merged cell, so its text will be centred over a number of columns.
A cell address in programs such as Excel normally starts with a letter (or more than one letter, if you use more than 26 columns), followed by a number. For example: A13, D53, AD1003.
