Although plants are complex organisms, the position and shapes of cells, tissues, meristems and organs establish themselves through regular and repeated processes. The cell constitutes the elementary structural and functional unit of these processes.

Cells are capable of synthesising new proteins and through intercommunication they maintain a large variety of genetic activities and trigger specific developmental programs. Therefore, a model of the networks of cell-cell interactions is essential to describe how new organsand tissues are initiated and regulated by environmental signals. The development of multicellular models is providing a fundamental understanding of the functioning of meristems that is central to explaining the plasticity of plant responses to changes in environmental conditions.
