The main difference between the two is that a function provides the ability to RETURN a value when it is completed, while a stored procedure does not. However stored procedures will usually populate tables with data, or 'return' values in out parameters. :)

It's like in all programming languages: a function returns some usefull data, which can the be used in other functions or programs. A procedure is a self contained mini-program: it has a start and an end, and, it may use other procedures and functions to do it's job, but the what it returns is usually less important. A procedure can be a standalone thing, a function cannot.
