To be more specific, the x on directories means search, not execute.

It means you can search. (Do an ls for example) wildcards not
withstanding. Without the x, you can't ls /dirname/filename and see
a result but you can get to the file /dirname/filename with an editor
or viewer for example.

For web engines like Apache and Netscape, the search is required for
the application to access the directory.

The best thing to do is set the directory to 755 (drwxr-xr-x) or at
minimum 775 (drwxrwxr-x).

The first group of three after the dir identifier (the first
character) mean user, the second three are group and the last three
mean everyone else (or other or world). So drwxr-xr-x means The owner
of the directory can write files into the directory and group and
other can search and access those files. (x = search, r = access).
