Leaf Structure

잎 구조

Definition

The arrangement of tissues in a leaf, including the epidermis, mesophyll, and vascular bundles, optimized for photosynthesis.

Detailed Explanation

Leaf architecture reflects a balance between maximizing light capture, CO₂ uptake, and water retention while minimizing heat stress and herbivore damage. Shade-adapted leaves are large and horizontal; sun-adapted leaves are smaller and angled. The spongy mesophyll layer contains air spaces that facilitate gas diffusion. Leaf economics traits — specific leaf area, nitrogen content, and lifespan — predict plant strategies across the world's biomes.
