The unramificated plant body can be regarded to be built-up with 3 parts.
These are seed lobes, stem, and inflorescence: two spheres, a cylinder,
a hemisphere. |

A vascular unit is defined by 3 units: the primordium and it's supporting
predecessors. Three spheres, one triangle. |
The S-curve for growth processes is used to calculate relative growth for primordia and stem. Initial primordia on a premature stem are big compared with their substratum.
Primordia on an initial sunflower head are small on the enlarged apical
dome. |
Fine-tuning in positioning is a local problem with 3 influences. |
