In tree architecture, which structure primarily supports twigs?

• A. Leaves
• B. Bark
• C. Branches
• D. Roots

Answer: (C)

Twigs are the small shoots that grow from buds on branches, so they hang from the branch framework. The branch is the main load-bearing element in that part of the tree, providing the attachment points, stiffness, and orientation needed for twigs to hold leaves, buds, and fruit. The trunk and roots play larger roles in overall stability and nourishment, while bark is protective rather than structural support, and leaves attach to twigs rather than carrying them. So twigs rely on the branch as the primary support structure.
