You need to use the grid_rowconfigure and grid_columnconfigure
methods of the containing frame, specifically the 'weight=' option.

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(1, weight=1)

See the Tcl/Tk documentation under 'grid' for more information,
including other useful options for the rowconfigure and
columnconfigure methods.
