Most trees would grow straight toward the light source if they could, gravity is one of the thing holding them back. And the cross-sections would be more slender & circular than usual because they don't need to form reaction wood to resist gravity.
Some plants have more specific gravitropic response and it's harder to predict in that case.

Reply to How would a monocot/dicot and a woody plant grow differently in zero gravity? Would the woody plant grow straight or does that require gravity? by Jade_Mans_Eyes
