What happens to plants if there is no gravity?

Plants need gravity, and many seem to need a rotation as well. The growing tip of a plant (apical meristem) grows in a spiral, which when you think of it is a pretty clever way to continue the construction.

Flanders and Swan sing of the "left-handed bindweed and the right-handed honeysuckle" [Forgive the lack of literary accuracy.] and it is true that by rotating a plant slowly counter to its natural spiral, this damages the plant growth.

Experiments of the nature you suggest have been done in the space station.
