You need the execute bit set on directories if you want to be able to switch to that. (The filesystem type doesn't really matter.)

chmod u+x ./apache

                        the directory.

                        directory and access files in that directory by name

                        (such as Web page files).

The Wikipedia article is worth reading and says

The effect of setting the permissions on a directory (rather than a file) is "one of the most frequently misunderstood file permission issues" (Hatch 2003).
