A student was given two permanent slides, one of binary fission in amoeba and other of budding in yeast. He was asked to identify any one difference in the nucleus of the two. One such difference, he indentified correctly was

The difference in the nucleus of amoeba and yeast was that, in amoeba, there are presence of two nuclei, one in yeast cell and one in its bud. This is because in centrally constricted amoeba looks like this where the stage 4 and 5 divides amoeba centrally constricted. However, in case of yeast cell, the parent cell of yeast has its own nucleus and the attached bud also has one nucleus. So, it has one nucleus in yeast cell and one in its bud.
