CHAPTER IV ON THE INTERNAL FORM AND STRUCTURE OF THE CELL

    1. On the central spindle, in the position of the equatorial plate, there has appeared during the migration of the chromosomes, a 〜cell-plate〝 of deeply staining thickenings (Figs. 50, 51). This is more conspicuous in plant-cells. {176}
    1. A constriction has meanwhile appeared in the cytoplasm, and the cell divides through the equatorial plane. In plant-cells the line of this division is foreshadowed by the 〜cell-plate,〝 which extends from the spindle across the entire cell, and splits into two layers, between which appears the membrane by which the daughter cells are cleft asunder. In animal cells the cell-plate does not attain such dimensions, and no cell-wall is formed.
