Adhesion of water molecules to vessels or tracheid walls to fight gravity is more important when there is not a lot of transpiration; what does a greater surface area to volume ratio look like in terms of tube diameter. Relate this to vessels vs tracheids. In the circumboreal forest regions (North Canada, Russia) what types of trees do you mainly see, angiosperms or gymnosperms? (Gymnosperms typically have no vessels, only tracheids; whereas angiosperms have both vessels and tracheids]) Is the vascular tissue properly adapted?
