Identify the parts labelled A. Since it occurs in the apical regions of the plant, this type of meristem is known as apical meristem. They do not originate from the embryonic stage. Secondary Meristem: Secondary meristems are the meristematic tissue arises from the permanent tissues. Tree Cross-Section. All meristems were accurately and precisely assigned from 841 DDI-selected marker genes , revealing that DDI is an extremely robust tool to quantify the meristem maturation state and that the relative maturation state of each meristem can be captured solely on the basis of gene expression profiles. Characteristics of Meristematic Tissues. Activity of lateral meristem increases the width of plant organ so it is responsible for secondary growth. Traductions en contexte de "méristème apical fut" en français-anglais avec Reverso Context : Au moment où le méristème apical fut tué par le froid, les bourgeons n'étaient pas encore près de s'épanouir.
