The process of nuclear reorganization in protozoa in which the nucleus divides, each half undergoes a maturation, and the tw persisting functional nuclei reunite is known as: a) autogamy b) autolysis c) autoregression d) autotomy
option a. In a examine of the nuclear conduct of Paramecium aurelia, a manner of self-fertilization, autogamy, has been found and traced thru its crucial steps. Autogamy is the counterpart, in a unmarried animal, of conjugation. In autogamy, 3 micronuclear divisions cause the formation of the gametic nuclei. These divisions are taken into consideration to be maturation divisions. The first department is characterised through a outstanding boom withinside the length of the 2 vegetative micronuclei and the incidence of lengthy thread-like crescents. The 2d department effects withinside the formation of 8 nuclei, variable numbers of which hold to divide giving upward push to the capacity gametic nuclei.
