Anatomy of fern fronds. The anatomy of a fern frond is relatively simple. They have a stalk which connects the base of the frond to the rest of the tree and runs along the entire length of the frond to the tip. The stalk can be separated into two parts: the stipe, which is the section of the stalk before any leafy part of the frond, and the rachis, the section with leafy tissue.
When entering a range of cell references as an argument for a function or when creating a chart, in addition to typing in the range manually, the range can also be selected using pointing. Ranges are identified by the cell references or addresses of the cells in the upper left and lower right corners of the range. These two references are separated by a colon ( : ) which tells Excel to include all the cells between these start and end points.
The key to formulas in Excel is cell references. Cell references tell Excel where to look to find the values it needs to calculate the result of a formula. Cell references can refer to one cell, a range of cells, or even entire columns and rows. Let's take a look. Every cell in an Excel worksheet has a unique address. The address of each cell is defined by it's location on the grid. The address B7 refers to the cell in the seventh row of column B, the address D6 refers to the cell in the sixth row of column D, and so on.
