As far as I know it was in the ROM on the
motherboard.
If you turn the machine on with no disk in the drive and no cartridge in
either slot, you get ROM BASIC.
There is also a more advanced BASIC on a cartridge. If you turn the
machine on with the BASIC cartridge in a slot, you get cartridge BASIC.
This is not a guess. This is how my PCjr behaves.

I doubt that the catridge BASIC by itself is a true superset of disk BASIC;
I think you have to have both the disk and cartridge to get everything.
I don't think the cartridge includes any of the disk I/O statements
and functions.
But the manual is at home, so I can't check it at the moment.

ROM BASIC = Cassette BASIC, subset of BASIC included on all Family Ones and
PS/2 through 8570. Able to load software from, save files to cassette. Also
handy on later models for twiddling the CMOS in the event of hosed setup
preventing boot, etc.
DISK BASIC = A "loader" that hooks into the BASIC interp. on the ROM cart.
Cartridge BASIC = The real honest-to-goodness BASIC.
