  We present significantly advanced studies of the previously introduced
physical growth mechanism and unite it with biochemical growth factors.
Obtained results allowed formulating the general growth law which governs
growth and evolutional development of all living organisms, their organs and
systems. It was discovered that the growth cycle is predefined by the
distribution of nutritional resources between maintenance needs and biomass
production. This distribution is quantitatively defined by the growth ratio
parameter, which depends on the geometry of an organism, phase of growth and,
indirectly, organism's biochemical machinery. The amount of produced biomass,
in turn, defines the composition of biochemical reactions. Changing amount of
nutrients diverted to biomass production is what forces organisms to proceed
through the whole growth and replication cycle. The growth law can be
formulated as follows: the rate of growth is proportional to influx of
nutrients and growth ratio. Considering specific biochemical components of
different organisms, we find influxes of required nutrients and substitute them
into the growth equation; then, we compute growth curves for amoeba, wild type
fission yeast, fission yeast's mutant. In all cases, predicted growth curves
correspond very well to experimental data. Obtained results prove validity and
fundamental scientific value of the discovery.
