Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary reinforcement mechanisms?Interlocking wood grain and embedded knots enhance mechanical strength and toughness
2. What is the ecological role of canopy?Strong branch attachments support canopy development, crucial for biodiversity and ecosystem services
3. What are the three main types of branch attachments in trees?Branch attachments are grouped into three main types. They differ because the buds that start the branch are in different places on the trunk, which changes how the wood grows and how strong the joint is.
4. How do trees make their branches strong?Trees make branches strong by weaving the wood grain together at the joint, which spreads the force. They also have knots inside the joint that act like tiny dowels, giving extra strength.

Cambial Activity: The growth of vascular tissues (xylem and phloem) from the cambium layer.
Biomechanical Properties: The physical characteristics of biological materials related to their mechanical behavior.
Stress Concentrator: A point or region in a material where stress is significantly higher than the average stress.
