Blog Post Image: The secret math of plants: UCLA biologists uncover rules that govern leaf design

Leaf thickness and cell size. Transverse cross-section of a very thin sunflower leaf (Helianthus annuus) to a thick tea leaf (Camellia sasquana). Along with total leaf thickness and leaf area, the leaves differ dramatically in cell size and in the thickness of cell walls according to specific mathematical equations newly discovered by the UCLA research team.
