The differentiation of parenchyma is mainly concerned with the living substance and the non-parietal products of elaboration. These tissues occur in all places where the plant development did not induce more specialized differentiations or, to use another expression, they constitute the fundamental tissue of all organs, at least when they are most active. Due to this distribution, parenchyma have been compared to the conjunctive tissue of animals. This comparison is quite inadequate if we consider that parenchyma along with meristems are the main sites of the biochemical activity of the plant. Therefore, they are the first to be discussed.
