Why is a stem and leaf plot called a stem and leaf plot?

A stem and leaf plot is called a stem and leaf plot because it is a table where each number in a set gets broken up into stems and leaves.

Stem = the first digit, or digits
Leaf = the last digit 

Ex: The stem of 32 would be 3 and the leaf would be 2.
