A Note on Significance of Cellular Interaction in L-system

It will naturally be expected that the number of necessary states for a PDIL system G_I is not greater than that for a PDOL system G_O such that G_I and G_O generate growth processes which are equivalent in a certain sense. Intention of this short note is to indicate a fact that existence of cellular interaction compensates or reduces the number of necessary states in comparison with interactionless system. In this note, for the sake of simplicity, we treat the propagative deterministic L system, while generalization is expected.
