Abstract:
Apical cells on the verge of dividing, or having recently formed a new segment, or actually dividing, are not uncommonly encountered in bryophytes and pteridophytes. This is interpreted as evidence for the "classical" concept of active apical segmentation in these plants (versus the concept of a quiescent apical cell). In certain species a polarized organization of the cytoplasm of the dividing apical cells is identifiable.

Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...
