There is a 'power- nap' feature on new mackbooks which keeps all the activity going even when the lid is closed.(eg. downloading email,backing up,syncing) Is there any such feature on ubuntu?

Yup. You can tell it to take no action when the lid is closed (Settings > Power). That's as close as you'll get to a "power nap" either on Ubuntu or Windows - the power savings of a "power nap" are negligible at best.
Other than that (really just leaving your laptop on), there's nothing you can do as far as I know.
Install TLP and configure your screen to turn off in lowest possible interval, you will get similar savings.
