Question
What is fission? What is the basic difference between fission in Amoeba and Paramecium?
✓

Answer

The mode of asexual reproduction in which a parent body splits into two or more daughter cells, each giving rise to a new individual is called fission.
Amoeba undergoes binary fission in which cytoplasm and nucleoid (DNA molecule) divide in any plane giving rise to two equal or unequal daughter cells without mitosis. However, in Paramecium, plane of division runs along the transverse axis of an individual.
