* Oorganogenesis. Representatives of new metamer organ cohorts can be created, according to micro and macro state evolutions.

* Plant Demand is computed, from all cohorts still in expansion.

* For each organ cohort, biomass allocation is evaluated, according to its sink value, the total demand and the available biomass.

* Organ sizes are computed using allometry rules

*Biomass production is computed from organ sources and sizes (usually the area of all functional leaves).

* The biomass produced is added to the remaining biomass if any, and stored in the biomass pool for the next growth cycle.

This animation illustrates the process involved in a growth cycle (Drawing and animation P. de Reffye, M. Jaeger, CIRAD)

Note that expansion is not synchronized with organogenesis.
Organ expansion can be delayed, typically in fruits.
It also operates on the organs created in previous cycles, until reaching the term of their development.
