Gnome 3 shell no longer has those things.
If you wish to see your applications, then go to the applications overview (Click Activities, then select Applications)
There are also extensions to Gnome shell that will put the places and applications back on the top bar.
yum install gnome-shell-extension-common gnome-shell-extension-apps-menu gnome-shell-extension-places-menu
You probably need to restart gnome shell after installing them.
