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.
Just a clarification, woody plants can include both monocots and dicots. Woody-ness (a shrub or treelike form) is a trait that has evolved many times independently in plants. Monocots and dicots refer to the number of seed leaves these clades possess (one and two respectively), amongst other differences.
