In order to achieve cellular integration, there must be regulation and control of the processes. This will be demonstrated at various planes. At the molecular level, the classical mechanisms of cybernetic and allosteric feedback are needed to control the biochemical pathways. In addition, cytoplasmic and nuclear processes are regulated downstream and upstream by macromolecular cascades that also involve nuclear-cytoplasmic interactions. Communication and transport is also required between all the other organelles in terms of specific molecules to modulate processes and recognition for vesicles transporting materials between them and to/from the cell surface. There is also this need in connection with the incorporation of host genes into the genomes of chloroplasts and mitochondria. With the advent of multicellularity, there is increasing specialisation to form tissues and organs composed of different cell types. In order to harmonise function of the organism, cells communicate by various methods transduced by the plasma membrane and interacting with intracellular cascades.
