🪵 Wood Formation

The vascular cambium produces xylem (wood) inward and phloem outward. Seasonal variation in growth creates annual rings - wide earlywood in spring, dense latewood in summer/fall.

Generation: 0
Total Rings: 0
Trunk Radius: 0mm
Current Season: Spring
Xylem Cells: 0
Cambial Activity:
Earlywood: Large cells, thin walls (spring)
Latewood: Small cells, thick walls (summer)
Annual ring: One year's growth
Heartwood: Dead, central support wood
