The apical cell of the first leaf and of the first root originate almost at the same time after the embryo reaches to the 32-celled phase.
胚胎在32细胞阶段后，第一叶顶端细胞与第一根顶端细胞几乎同时发生。
It fills and expands the apical portion of the cell and forces the nucleus into the slender basal portion.
它充满并推向细胞的顶部，迫使核移向狭窄的基部。
Root growth is mainly determined by cell division and subsequent elongation in the root apical area. Components regulating cell division in root meristematic cells are largely unknown.
根的生长主要取决于根尖区的细胞分裂和伸长，而调控根尖分生组织细胞分裂的成分很大程度上是未知的。
