The Software Update application is just a GUI frontend to the apt and dpkg backends in the command line, which actually maintain and manage the packages.

The ultimate underlying commands being run are about equivalent to sudo apt-get update when you hit "Refresh" or "Check for Updates". The about-equivalent command being run when you have all the packages selected in the graphical list of packages is sudo apt-get dist-upgrade, or for specific packages selected and others not selected, sudo apt-get install PACKAGE1 PACKAGE2 PACKAGE3 ... (where PACKAGE# is just a placeholder for selected packages).

Ultimately, apt-get update, apt-get upgrade, and the Software Update application are just different interfaces to the same goal - the updating of packages in the system, ultimately handled by dpkg in the end.
