"ls" (at least the implementations that I know of) use fts_open, fts_read ... to traverse a file hierarchy. These are "non-recursive" methods which maintain a list of the visited directories internally.

Yes, the formatting of the output is the only difference between ls -1 and ls without any options.
From the ls manual on my system:
-1 (The numeric digit "one".) Force output to be one entry per line.
This is the default when output is not to a terminal.
This is also a POSIX option to the ls utility.
The manual for ls on your system is bound to say something similar (see man ls).

ls -1 lists one file per line. By default, when it’s outputting to a terminal, ls lists files in columns, whose number varies depending on the length of the file names and the available space on screen.
To find this kind of information, man ls works better than ls --help. (This is true for most commands.)

Instead, bash shell creates an exact copy of itself by calling clone() system call and then executes ls so that ls resources are written to this new process and not to parent process.
