The execute permission, when applied to a directory, allows you to
change to that directory with cd:

<http://www.isu.edu/departments/comcom/unix/workshop/files.html#perms>
Execute permission
        For a file, execute permission allows you to run the file, if it
        is an executable program, or script. Note that file execute
        permission is irrelevant for nonexecutable files. For a
        directory, execute permission allows you to cd to the directory,
        and make it your current working directory.
