Question

Four stages of binary fission in Amoeba are shown below. The stage at which nuclear fission and cytokinesis are observed is, stage
(1) I
(2) II
(3) III
(4) IV

Answer 1

Answer:

Cell divisions in amoeba involves two important events i.e Karyokinesis (nuclear division or fission) and Cytokinesis (cytoplasmic division).

After replicating its genetic material through mitotic division, the parent amoeba cell divides into two equal sized daughter cells.

Karyokinesis is the process of the division of the nucleus. It involves the separation of the daughter chromosomes into two daughter nuclei. Karyokinesis is usually followed by Cytokinesis.

Cytokinesis is the process of the division of the cytoplasm. It involves the separation of the daughter nuclei into two daughter cells. Cytokinesis occurs immediately after mitosis.
