Bell came to the crease with his team in deep trouble on 28-3, but his innings of 109 that spanned just over five hours, frustrated the Australians when they would have scented an England capitulation.
Jonny Bairstow hit 67 and contributed to a fifth-wicket partnership of 144 with Bell. But his late dismissal to a full toss from part-time leg-spinner Steve Smith, and the subsequent fall of Matt Prior, undermined England's rear-guard effort as Smith ended with 3-18.
