Division of Function in Eukaryotic Cells

It seems logical that the distribution of genes among the nuclear, mitochondrial and plastid genomes of the cell may vary from one species to another or, at least, among larger phylogenetic subdivisions. The eukaryote 

Among social insects, the unit of selection and evolution in the community and the tasks within this community are sorted out in various ways among different groups. So, in the case of eukaryotic cells, it seems reasonable to expect that there is a variety, rather than a single successful solution to the problem of subdivision within a single cell. 

Just as in the study of evolution of organisms, students of organelle biology must look for principles of organization and function. Appreciation of the dynamic state of intracellular relationships may make it easier to recognize the principles.
