Plants maximize strength while reducing materials by incorporating tetrahedral elements that can be stacked in hexagonal containers.
"Nature has provided many packaging methods to protect plants and animals against physical impact. The design often uses a minimum of material while offering a maximum of usable space. Tetrahedral elements which can be stacked in hexagonal containers without any waste of space are frequently found in plants." (Tributsch 1984:22)
