A plant is a multiscale network of botanical entities and organs (leaves, internodes, fruits, roots) connected together to build its architecture and whose functioning results in biomass production and partitioning. All organs may be a source of biomass (even sometimes internodes). The seed contains the first reserve for the initial growth, and the leaves are usually the specialized organs for biomass production. Conversely all organs may be sinks for biomass, because they use it for their expansion. For the production of biomass, plants take water and nutrients from the soil through the root system and carbon dioxide from the atmosphere through their leaves.
