How do plants turn towards light?

I'm a physiscist, so I'm not very good at these bio-matters. Me and my
girlfriend (who's a chemist and say's she knows better) have been
discussing something I think I've read in som semi-scientific magazine
some time ago.
Plants turn towards the sun (or other illumination), because the cells
not exposed to the light, split more quickly. This makes the plant bend
against the light.
Is this idiotic, as my girlfriend says? In that case: What makes them
turn and bend, the way they do?
