This object hierarchy is explained in the MATLAB documentation:

To post it as an answer, not only as comment:

This is explained in the documentation, see doc groot

You can search in the documentation also:

docsearch root

A short summary: The root object is the parent object of all figures. Some of its properties belong to the Matlab session, as e.g. the CurrentFigure. Some concern the current computer setup as the ScreenSize or the PointerLocation.

In older Matlab versions the graphics handle of the root object was 0. See:

get(0)
get(groot)

[Jordan Mandel]

Random question: I use the 'DefaultFigureVisible' property of groot (I actually use '0') to generate figures while a script is runnning so that I can work on other things on the computer without constantly being interrupted. But this is not listed among the properties of groot when I do get(groot) . Is DefaultFigureVisible a hidden/undocumented property?

[Steven Lord]

It's not really a property of groot at all. It's a way to tell groot that you want to set the Default 'Visible' property for all new Figure objects to a specific value. See this documentation page for more information.
