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.
A âcell referenceâ means the cell to which another cell refers. For example, if in cell A1 you have =A2. Then A1 refers to A2. Letâs review what we said in Lesson 2 about rows and columns so that we can explore cell references further. Cells in the spreadsheet are referred to by rows and columns. Columns are vertical and labeled with letters. Rows are horizontal and labeled with numbers. The first cell in the spreadsheet is A1, which means column A, row 1, B3 refers to the cell located on the second column, third row, and so on.
