The mitosis was definitely decreasing the last time I checked you.
Figures 99 and 100 are equatorial plates of the first mitosis.
Diploid (2n) chromosome numbers were determined from cells in late prophase and metaphase of mitosis.
An early anaphase of this mitosis is shown in figure 19; here the small chromosome is already divided.
As the chromatin begins to condense for the second mitosis, disintegration of the element x becomes apparent.
Telophase of second mitosis, showing masses of chromatin left behind in cytoplasm.
Each of these divides again by mitosis (the chromosomes splitting lengthwise), the half or haploid number remaining.
Mitosis, then, is a form of growth of a mass, not a generation of new individuals.
This increase is therefore reached at an earlier period in the larger wound since the process of mitosis is more rapid here.
As noted, in fission the meganucleus divides by direct constriction; each micronucleus by a mode of mitosis.
