Components of a Tree
Ancient trees that reach for the sky remain vibrant after a century of trials and tribulations, and the secret lies in their structural composition. From the deep roots that penetrate the earth to the leaves basking in the sun, each organ works in harmony like a precisely crafted gear, constructing a miraculous kingdom of plant survival wisdom.

Root System Trio
The root system that delves into the soil is like the internet of nature, with the main and lateral roots forming a three-dimensional network. The surface fibrous roots act as mini water pumps, absorbing 200-400 liters of water daily; the middle layer of transport roots, filled with vascular bundles, have a conveyance speed comparable to high-speed trains; and the deep storage roots store enough starch to support the tree through three dry seasons.

Five Layers of Trunk Armor
The seemingly simple trunk hides five layers of protection: the outer layer of bark acts as fire and insect resistance, the phloem transports sugars at a speed of 100 cm/hour, the cambium layer thickens by 3-5 centimeters annually, the sapwood can transport water up to 115 meters high, and the heartwood accumulates phenolic substances that keep rosewood from decaying for a thousand years.
Three-Dimensional Branch Crown Modeling
Branches follow the Fibonacci sequence in spatial arrangement to ensure that each leaf receives optimal sunlight. The auxin regulation of the apical meristem causes branches to form a 45-degree golden angle, which maintains the center of gravity balance for a century-old tree.
Leaf Photosynthesis Matrix
Each square meter of leaf area can convert 18 grams of glucose daily, and the 300,000 stomata on the back of the leaves form an intelligent breathing system. The thylakoid membrane in the chloroplasts can unfold to an area 200 times that of the leaf surface, making the forest the green lung of the Earth due to its ultra-efficient structure.
From the microscopic cellular organization to the macroscopic morphological construction, trees interpret the wisdom of life with their exquisite structures evolved over millions of years. When we look up at a giant tree 30 meters high, we are actually witnessing the architectural奇迹 of the plant kingdom. Protecting these green engineers is akin to safeguarding the foundation of the Earth's ecosystem.
