The spiral phyllotaxis here presented is the most common described a divergence angle of 137.5 degrees. it is related with phi, 0,618^2*360=137,5. This whorled pattern rises from the same node moving on divergent directions.

The water is repelled through a path that arrives in the trichomes. It then is absorbed through osmosis, where it causes the trichome wing cells to move according to the water. Thids leads the water through the pedicle where it then move to the aquifers and is stored, going back to its natural position.

[POROSITY]
Porosity Study Based on Cast Shadow of the ‘Celll’ Structured Domes Through the porosity studies of the cast shadows, we can see how although heavily dense cells may cause a stronger shadow, the multilayered shapes may result on a more complex light path and the thinner optimized packing single layers (circle packing and voronoi diagram), bring the lightest result in overall shape and porosity.

After a variety of studies are done, an analysis show a range of different solutions that may cause more edges. For this study only 3, 4 and 5 edged elements were selected. As they may have better architectural applications.
